Audio input - Raspberry Pi Q&A, Help & Troubleshooting

Has anyone figured a way to get audio input using the gpio pins. Or any other way that's not USB?

Yes people have, I would suggest taking a look a these well written guides from adafruit and other places on using inputs, and audio inputs using GPIO:

Thank's for those links, shimp208. Maybe you know is there a way to use HDMI output as input(eg. to capture video)

Broadcom's info page says:
High performance display outputs. Simultaneous high resolution LCD and HDMI with HDCP at 1080p60

For embedded electronic, this usually means no input.

You can't. Except for hdcp strippers like hdfury or hdcp-free capture boxes, the only devices accepting HDMI input are monitors and projectors.
Let me guess, you were trying to put up an HDMI recorder...

This response is a little misleading. Those links are how use GPIO pins for controlling audio samples not actually using them for audio input.

That is true now that I reread them though those links are almost 6 years out of date . If you have any further Raspberry Pi questions feel free to reach out to me.

Miracast set top box!!

Hey,
I've just seen a Miracast set top box from Netgear. This could be the solution to the missing HDMI out of the Nexus 7!
http://www.netgear.de/products/home/hometheater/media-players/PTV3000.aspx
Can anyone remember nVidias demo?

It sais you need aNotebook, Smartphone or Tablet with Intel® WiDi oder Miracast™,
does our Nexus 7 has Inel WiDi or Miracast?
Is it just Software or do you need special Hardware Support for that?
It would be nice if i could stream from my Laptop or my Galaxy SII as well.

Did you watch the Video? The Tegra 3 can do it. I don't know more... but I hope there will be a software update to do it.

i do know the tegra 3 is miracast capable i dont think i can post a link so ill just post what i found, this is dated july 27 2012.
Nvidia, a member of the Wi-Fi Alliance, announced that it's supporting the new Miracast WiFi-Direct based protocol which is expected to launch by the Wi-Fi Alliance within the next few months.
For the uninitiated, Miracast will be an open standard, so any mobile device or display manufacturer will be able to implement the technology. It will also be a direct competitor to closed eco-systems like Intel's WiDi and Apple's AirPlay which enable users to wirelessly stream videos and games to external displays.
There are also other open standards for streaming media such as DLNA, but these are plagued with interoperability issues that have limited their traction in the market place. To address the limitations of these solutions, the Wi-Fi Alliance created its upcoming open wireless display standard called Miracast.
"Underpinning the Miracast specification is Wi-Fi Direct – a specification defined for peer-to-peer, direct wireless connectivity between devices," Nvidia said on Thursday in its whitepaper. "Miracast Certified devices will be able to connect with each other directly, without the mediation of a wireless access point, by leveraging the functionality introduced by Wi-Fi Direct. When two devices connect with each other directly, one assumes the role of the source (transmitting device) and the other becomes a sink (the devices receiving and rendering the content to the user)."
Nvidia said that it has developed a Miracast wireless display stack that is Tegra 3 optimized and can be integrated into the Tegra mobile platform. This source-side solution enables tablet and phone OEMs to implement a Miracast certifiable product by combining the Tegra application processor and compatible Tegra Android BSP package just as they do today.
"The Tegra optimized Miracast solution is comprised of two major components – the multimedia (video/audio) processing block and the industry compliant wireless display networking stack," Nvidia explained. "The multimedia processing block takes advantage of Tegra’s multi-core graphics engine and dedicated hardware video/audio codecs to accelerate the decoding of video content, render graphics surfaces and perform the final compositing operations before encoding into a H.264 bit stream to be wirelessly transmitted."
We are miracast certified, however there needs to be an app to activate this tech for us, I believe, but if they have the set top box, chances are there's an app for it, too.
All I can say is, yay! Step in the right direction. -Ara

Miracast is a new standard for wireless display. So basically a mirrored image or maybe a second screen. I'm hoping I could widi a video and control it all with my tablet/phone.

That's how you play full hd shows/movies/music with no dramas its been around for ages. Best part is wd keep updating the firmware so it plays anything I throw at it.
Gaming well you can't do that but if you can't see the 7" screen right in front of you well you'd probably find it more beneficial to invest in glasses.
It also has some other benefits too, bubble upnp is one of the best things I have come across.

The difference is that only the ptv3000 is miracast capable. At least that's what the product page says. I've already written an email to net gear Germany to ask them about this box. As soon as I have an answer I will post it.

Got it. I didn't see the video.
So I am assuming this is the first TV Box(similar to like a Roku or something) that allows us to wirelessly display our Nexus to our HDTV? That's what I am seeing. Also it's only in Germany at the moment.
But the question is, do our Nexus 7's natively support something like this? I am assuming this needs development, like an app or software update.
Any news on this?
Not sure I see the point of this. I already have a WD Live that can stream all my video from my PC to my TV. Why would I put video on my N7, then send to my TV when I can just send it directly to my TV? Even the 16 GB N7 can maybe just barely hold a decently encoded movie at full 1080p. I just don't think I have any content on my N7 that cannot be sent to my TV in an easier, higher quality way.
Edit: Been thinking about this. Seriously, what do you use it for? The only thing I could come up with is letting your friends watch you play a game on the tablet or something. Every other scenario I can think of has a better solution.

It's not only for videos. I have a tf101 transformer and used it to give presentations at the university with HDMI out. The point is to mirror the screen content of your device and not only play back media.
And it looks promising with the low latency.

Emulation Gaming. Plug your tablet up to the TV and use a PS3 gamepad for true retro couch gaming.
I don't stream movies and such, as I'd rather just watch them off the device.
I'm curious about this as well.
Here's some more info about it that I dug up from arstechnica.
In most cases, Miracast can be implemented in software alone, Robinson said. It has a head start, because Android already supports WiFi Direct since version 4.0 . But hardware modifications will help optimize devices for the type of compression, decoding, and encoding Miracast equipment will have to perform, he said.

I've been watching for (complete) Miracast solutions for a while now. This capability is already starting to play a big role in education on the iPad courtesy of AirPlay mirroring. I have no idea why other vendors are sitting on this.
Anyway, the NTV200S is supposed to be compatible with a firmware update. Some more info here:
http://www.anandtech.com/show/5957/...otv-pro-ntv200s-widi-and-media-streamer-combo
Another big feature that miracast will add is the ability to display your phone's display on your tablet. This way you could always be on your tablet, but at anytime access all the features of your phone.

Google is looking for your feedback!

I just got off the phone with Google technical support. In fact I spent about 40 minutes on the phone with them discussing bugs/problems and feature suggestions with the representative. Google is actively looking for our feedback to improve the devices so feel free to give them a call and contribute your two cents.
Google Play Support: 855-836-3987
Issues/Features I had contacted them about:
Low volume in Netflix
1080p content scaled to 1920x1200 on a 16:10 aspect ratio monitor (other devices scale properly)
Feature request to add an option for auto power off of the device after a specified amount of inactivity
I wonder if Google read these forums about their devices?

Just left feedback about Netflix and Chromecast in general specifically:
The need for the Chromecast app to also act as a universal remote to play/pause/next/prev/stop playback from any source without having to go back into the app to make the notification appear.
A widget with basic controls for the above.
Netflix being able to auto-advance show episodes.
Being able to turn off the TV.

How can that work? I can't image going to my wall unit, opening up the door, reaching behind my Onkyo surround sound receiver, finding the Chromecast amongst a bunch of wires and pressing a button to turn it on. Can you imagine asking the wife to do that?
I hope they don't implement this feature.

Sorry I guess I should have been more specific...
It wouldn't actually power down the Chromecast, it would simply disable output of the video signal to the TV/Monitor. If your TV/Monitor has an "auto power off" option when no signal is present, then it will turn itself off. The Chromecast would turn the signal back on when a new cast has started. Pretty much the same idea as the monitor power saving features on a PC. The last thing I want to do is leave my TV/Monitor on all night after watching a show before bed.

If your TV has a usb port on it, you can power the Chromecast by plugging in its power cable to that usb port. When I shut off the tv, the Chromecast shuts off too. That's what I do with mine.

I have my Chromecast plugged into my AVR and it does the same. When I turn the AVR off the Chromecast also turns off.
I think the actual physical Chromecast device is just a transitional product. Future TVs and AVRs will have this software built into them.

I have my Chromecast set up this same way on my 40" TV in the living room. But in my Bedroom I have my Chromecast attached to a 28" computer monitor (so there is no remote). My only option for turning off the unit is to get out of bed and turn the monitor off directly. This previously worked just fine using my media center PC in the bedroom as the PC was smart enough to cut signal to the monitor after inactivity. Such a feature is not currently possible on the Chromecast (hence why I had requested it).
Not sure if this is the right place to ask, but does Google consider adding HLS support ?
Or at least provide guidelines on how to map existing M3U8 playlists that we have to DASH .MPD ?
Thanks !

If you have a voice with Google or work for them...let them know that all they got to do is put that final SDK out with the quickness. With the dev community as a whole there is and will be a slew of apps that would project this $35 dollar piece of hardware to the moon. People would say Apple what? Roku what?
Just my $.02. I am sure u and/or Google knows this already though. I just can't contain my excitement knowing the potential that the chromecast has.

I just plugged the Chromecast in, and it updated (had been sitting on the shelf for a while). After the update, the same problem is exhibited. I have 2 aspect ratio options in the monitor settings, "Full" and "Fit". Both provide a 16:9 1920x1080p signal stretched to the 16:10 1920x1200 resolution.

I am using an NVidia Shield 2015 and 2017 model, both 16GB. However I am not using them on the 32 inch monitor with the 16:10 aspect ratio so I can't comment on whether they would do the same thing with their signal. I actually got a new TV a month ago (Samsung 60KS8000) with 4K and HDR. Shield 2017 had 0 issues streaming a 65mbit/s bitrate HEVC/x265 movie from Plex on my local desktop, I was blown away at the quality.
The other pro to the Shield is it has Gamestream if you have an Nvidia card and a decent network. It also has a Chromecast baked in, so I didn't lose any features when I upgraded from my Chromecasts.

We have no idea or enough info to even try and help. It's like saying my car won't start but my neighbors does, what's wrong?
What TV do you have the issue with? Is it hooked up directly to the TVs HDMI port?
Have you tried a different HDMI cable?
How do you have the Chromecast connected, USB or outlet?
Dose it work with other HDMI TVs/monitors on YOUR network?
Have you tried casting from and Android device, PC or both?
Basically you have to give some details. All we have right now is:
1. older TV
2. 720p
3. Audio but no video
not much to go on.
I guess if it an older TV it's possible there's some kind of incapability.
I am having the same problem so I'll try and provide more info.
I am using Chromecast in hotels. These TVs have not been updated in ages. The current one I am checking on is a LG 32LC5DC TV. I believe it is a known issue that Chromecast can only display 1080p format. So basically the video does not work but audio does.
What I am curious about is that it worked one time on the same TV model. For the life of me, I cannot get it work again.
My chromecast works fine on an older 720P Samsung plasma that does not support a 1080P signal input. Not sure if the tv will accept 1080i.
Most likely the Chromecast is relying on the TV to report back via HDMI whether it supports 720p or 1080p, and then it selects the appropriate resolution. But if the TV is too old, it might not report anything, causing the Chromecast to default to 1080p.
I don't think the Chromecast does any auto-detect at all. On my 720p TV the info screen clearly shows that it's getting a 1080p signal. So Chromecast sends at 1080p no matter what, and if your TV does not display 1080p then it must be able to downconvert or it won't show any image at all.
In my experience the Chromecast does do some communication. I hooked it up to a VGA monitor through an HDfury2 (which doesn't scale) and the monitor reported a 720p (1280x720) signal.
Meanwhile my 1080p TV says it's getting 1080p.
On boot-up, the splash screen seems to be 480p, but I've never successfully gotten the Chromecast to output 480p past boot, despite disabling resolutions via EDID updates on the display end.

Thanks. I do know that Chromecast can output 1280x720.
Your TV seems to be one of the types where different HDMI ports have different capabilities (I hate that).
HDMI 1 seems to support both Computer and Video resolutions/timings.
HDMI 2 supports only Video resolutions/timings.
Make sure you have the TV on when you plug power into the Chromecast. That'll ensure it can negotiate the supported resolution properly.
If that still doesn't work, remove power from Chromecast, move Chromecast to the other HDMI port, then power up Chromecast and see if that works.
2 to 1 Odds it's the TV not the Chromecast.
And Hotels are notorious for disabling HDMI Ports on their TVs!
All it takes is one bad pin on the connector to make the entire input not work.

There really is no such thing as "hi-res headphones"..........There are just better headphones/earphones...

If you want in-depth reviews about specific head/ear phones, i'd suggest:

i know about head-fi , but i want something that works well on z3. for playing lossless files
yeah, basically any high quality wired headphones that can be driven by a smartphone will work. and if you decide to use a portable amp, then any headphones will work.

i have mdr-xb70 , are these any good ? any recommendations ?
I have never tried those so I don't know. There are a lot of good portable headphones, just check out headfi.org under the portable headphones section. I personally use Sennheiser MM-500X. It's bluetooth (with aptx) and wired for my phones. Sony's current MDR lines are pretty good too. Just a little too much bass emphasis for me, but it's just personal taste. It's hard to recommend headphones tbh.

LG Quad DAC Tips, Tricks, Etc...

Howdy All,
For those who have had a LG V device in the past you'all know what's coming - how do we trick the quad DAC into high impedance mode (HIM) or AUX mode?
For those who don't know here's a little background. The previous LG V series phones have had a very nice DAC and AMP setup which can almost meet the standards of audiophile quality. The thing was that in the later phones (V20 and V30 AFAIR) the software was designed to "smart switch" which mode the AMP was in. HIM and AUX mode settings had the loudest volumes and was corresponding to the headphone impedance value. The normal setting had the lowest volume designed for low impedance IEMs. Note that the AMP setting doesn't really have a bearing on sound QUALITY, just sound VOLUME. I'm guessing but the reasoning for this is to prevent blown IEMs and blown eardrums. I'm going to find the link for the old V30 quad DAC thread and some stuff tried and what worked in order to activate AUX mode and/or HIM. BTW having ROOT on the phone allows for adjusting this setting as needed, which is why I went with the unlocked version this time around. My pair of MrSpeakers Aeon Flows have low impedance but need power in order to drive properly and the AMP in the V series phones would only trigger normal impedance mode.
https://forum.xda-developers.com/lg-v30/help/modes-quad-dac-t3690567
So that brings us to the V40. Does it have a quad DAC? Yes it does. Does it have a smart switching AMP? So far my indications are yes it does. Do the old tricks from the V30 days work on the V40? I don't think that they do. I have multiple extension cables, which I use for triggering the AUX mode as well as an impedance adapter (50ohms I think). The old methods of using the extension cable, the adapter, and both don't seem to have an effect on the AMP setting. My Sony MDR-1As are much louder than my Aeon Flows...bummer for me.
UPDATE - Upon further testing with the help of this app: https://play.google.com/store/apps/details?id=com.apptrio.hi_fi_status I was able to trigger the AUX AMP mode and it kicked up the volume on my Sony's quite a bit! Unfortunately when I triggered HIM the volume of the sound did not change from the normal mode. Basically what I did was take a 2ft 3.5mm cable extension (male on one side female on the other) and plug it in WITHOUT THE HEADPHONE CABLE ATTACHED. Once the HIFI status app displayed AUX mode I then plugged in my HPs and BOOM, here comes the volume!
Anyways if you have anything to add or have any questions feel free to hit us up. When root is available I'll also make updates to this thread if need be.
Have a good one :highfive:
Is that why the volume is stuck at 75?

If you have your volume go up to 75 and it doesn't blow out your ears then it is due to the AMP being in normal mode.
I just say one thing:
Neutron player!
Demands some fiddling before you reach your preferred settings, but for me it's the best DAC player out there!

Have you tried the mobile version of foobar2000? As it's the preferred app for FLAC files and such on the PC, I imagine the mobile version is quite good as well. I wonder how it compares to Neutron Player. I definitely will give both a shot and compare.
On the note of music players, despite making fun of it (it's quite easy to do) and being certain it would fail, I recently converted to Tidal. The quality is really astounding, and the music library is almost as complete as Spotify/etc. Additionally, some albums are available as "masters" that are actually encoded with MQA!
Your right about Tidal. It sounds awesome. The price difference isn't worth it though.
Treesap! I'm comparing those players right now! I'm listening to metal (Tesseract), jazz (Yellowjackets), all flac, and so far I like both foobar2000 and Neutron. The built in player is not satisfying me yet, except for mp3 (I See Stars - Treehouse). Does anyone know if it's necessary to disable the built in effects to make other players work independently? That's what I did with v20. Just remember how different expectations and taste we all have in regards to music/sound
And maybe I should add that I'm just a regular user (with high demand on sound quality), who can't afford too fancy earbuds or extras right now. Any advice regarding good quality sound (budget price) earbuds would be very appreciated
Went back to Poweramp (poweramp-alpha-build-705) and so far it's the best one for me.
For anyone who didn't know, if you payed for the full version, you can upgrade it to high res.

So after fiddling for a while, Poweramp alpha 705 is tuned (for my ears) to perfection
If it can help anyone, I'll happily share?!
BTW, some interesting reading that made me understand more about hi-res and DAC:

Does Poweramp 705 perform better than LG's stock music app?

Well I'm sure there's some tech guys here who can give us the correct details, but for me the answer is yes! After tuning it up for my ears, the Poweramp does it in a perfect way. If I play mp3 or flac it's giving me perfect sound all over, compared to the lg app were I had to tune it up for individual files.
have any of you engaged the DAC for streaming, for Google music in particular?
there was mention by some last year that one DAC player and an add-on app could do that for Google music. i just don't keep much on my phone and streaming is my way, so I'm still looking at taking advantage where i can. I'm running V4A on a rooted V30 now and looking at the V40's development.

Poweramp improving and improving
(Poweramp-v3-build-805-uni)
I realize there probably isn't much benefit from forcing high impedance but I do want to do some testing with it among other things so I'm curious has anyone figured out any tricks to forcing it with an extension cable or anything of the sorts. I'm still trying to find ways and it looks like similar ways done to the v30 isn't working the same way for our v40's

What settings have you set your Poweramp to? The LG app is sounding better and much louder to me.

Hope the following can help, and also, please correct me anyone, if my way of thinking here is some way wrong or misleading.
A assume you've already taken part of the Poweramp forum?! It's the only way to get the hi-res add-ons. And you obviously have to log in to be able to download.
I'm not 100% sure about how poweramp and the built in eq interacts, but after fiddling for a bit, it seams like what I'm sharing here works best when it comes to volume and sound. Have in mind our individual reference of sound and of course, what kind of earphones/buds you have (this is based on flac files).
You can see I've put replay gain on max in Poweramp settings. You can easily change RG in the eq later to fit individual album.
If anyone else have suggestions, please don't be shy

Speaking of the DAC, does anyone know if the V40 has support for MQA? The V30 has it, and they recently added support for it to the Essential PH-1, but no mention of it for the V40, just "high quality Quad DAC". I suspect that it does, because they probably used the same chip for the V40, but I see no mention of it anywhere, so far.
