[Q] Line out audio question

I've searched the HD2 accessories forum and found some inklings of the question I'm asking, but none that quite hit at the heart of the matter. So, my question is this:
Does the HD2 (TMO US) send line audio out through the micro-USB port? I would assume it does, since the dock HTC sells for the HD2 has a 3.5mm jack in back, and it only plugs into the phone via micro-USB.
And my follow-on question would be, if the HD2 does indeed have line audio in the micro-USB port, does anyone know of an actual splitter accessory that splits out line audio and USB charging? I saw this device at AndroidCentral.com's store (sorry, my new account doesn't allow external links) (htc-3-in-1-usb-adapter/5A18A3571.htm) in another thread. But since it's mini-USB and HTC claims it only works for the phones specified, does that mean a gender changer (Daydeal.com, Product ID 31355) wouldn't work with it? Thanks for any info/experiences you folks have!

No one has any info for me?

I browsed around to see if i found anything on this also but i don't think it's possible since it's not a A/V port of any sort. as far as your second Q: The splitter would only be that; something to add additional port's on the device. ie: Since it's connected thru the Micro-sub and the splitter has a mini(assuming)-usb port, it can therefore be charged, Also add's an extra audio jack. (just examples)
Someone correct me if I'm wrong.

Thanks for the response. It may be that the HD2 by itself may not have line audio or any video out signal tied to the micro-USB port, but just the fact that that splitter exists for earlier HTC phones' mini-USB ports gives me hope that the line audio pin out is there. I mean, I'm not an electronics wiz by any stretch, but I think mini and micro USB only require 2 pins for power, right? And there's at least 4 pins there on a micro port.

The older HTC phones used the mini-USB compatible extUSB interface-where the top portion of the connector did the duty as the USB interface and the bottom portion of the connector was the audio interface. Between everyone hating to have a dongle to the emergence of microUSB as the industry standard put extUSB on the road to extinction.

Thanks for that. Makes sense, since they decided (for some stupid reason) to not add a 3.5 mm headphone jack to those phones. But what doesn't make sense is how they can give these newer phones great hardware, and tout their multimedia capabilities, and yet not add a functionality that Apple has had built in since their first iPhone. That's the main reason I still use it: because I don't want to carry two devices around.

Microphone n voip

Any workarounds for a voip app and microphone for a rooted book color?

the cool guys that know what they are doing are working on bluetooth, that seems to be the best bet to getting a microphone working with NC, cross your fingers!

what about a wired headset with a built in mic. does the nook have the connections to support this?

I think the two best options right now for voice applications are probably the Bluetooth and the slight possibility that the micro-USB port on the Nook seems to have quite a few extra pins on it, which may have left B&N open to a proprietary connector that would allow for additional device connectivity via the micro-USB port.
I've purchased a number of micro-USB adapters in order to plug various devices into the micro-USB port of the NC, with zero success (keyboards, USB headsets, mice, etc). Clearly that port isn't currently operating in that manner, and I'm sure there's a tech savy person that could drop in and give us a simple answer to why this is.
I was also curious about the headphone port possibly have mic capabilities, and was about to purchase a single post headset to test the theory, but then I took a (very unscientific) look at the headphones jack, and it would appear that there aren't enough ring connectors inside it to support an additional channel. Obviously the guys doing the tear-down would know far more about this than myself.
We'll see what turns up over the coming months.

Found this teardown post with spec list and it says that there is no mic input in the headphone jack. I know I read another teardown post which I cannot find that indicated the same thing. I agree that our best bet may be getting the bluetooth working.

Can you detail what sort of adapters you tried? Have you tried a gender changer (type a-a female-female) on the end of the nook cord attached to a keyboard?

Someone correct me if I am wrong but, in order for the usb to do something other than just charge and connect to the PC from the usb, you would have to activate USB host, which is not turned on in stock. Hence no of the fancy toys will work. There are a lot of funky pins on the connector so it may have to be some funky adapter, assuming you get usb host running. There are a lot of hackery potential, but until that project is completed, the wait for bluetooth continues.
Go Occip! (the guy hacking the bluetooth.)

This is what I've been thinking about. I don't have the ability to figure out how to activate the USB Host function, but I read several posts about how it worked on N1, D1, and Hero.
The thing I want to try is using a micro USB to 3.5mm minijack cable like those that came with the G1. It's the only thing I could think of that could logically be supported by the default system since it was necessary in 1.5 on that device.

I don't think anyone is using VOIP yet, but you may be very interested in this thread:

I'm running the CM7 image via SD card from that thread, and the Bluetooth works, and I can connect to my phone and my headset. Several people can connect to their standalone GPS units. Worth watching.

Anyone know if the micro USB port is even powered?
On a lot of phones, the USB connectors aren't powered by the device (like my HD2), so you have to hack together a proper setup that supplies power.

Mate 10 Pro connection to Kenwood DNX525/DNX516

Hello,
I have never been a chinese devices fan nor I will be. However, I've got my hands on the Mate 10 Pro a week ago and I'm using it and testing. I have to say it's not the best phone out, but has a lot of potential.
I thought it might be interesting and useful to give others some guide about connecting the Mate 10 Pro to a car head unit from Kenwood (2 versions I have already tested - DNX 525 and DNX 516). I've smashed my head to the walls looking and reading for a proper solution to connect it to the radio car unit and I couldn't find anything. Main reason is because both Kenwoods are using a HDMI <-> Micro-usb cable and that's ONLY for older devices (until USB-C came on the market). So, basically, if you're trying to get an adapter USB-C to Micro-usb WILL NOT WORK! You have to use the above cable hdmi to usb-c!
1. Look for a HDMI splitter - 1 x father and 2 x mother so you can connect 2 devices at the same time (just like the one here: http://www.vivanco.com/Homepage/Products/Audio-Video-Antenna-Cable/Video/HDMI-Adapter/vivanco-42144-hdmi-splitter-1-2-black-0-5m.html?id=nsession;
2. Open the radio car unit and disassemble the original HDMI <-> Micro-usb and connect the above splitter;
3. Connect BOTH HMDI cables (the original one and the second one);
4. You'll have to find a solution to get both cables to the front of the IP so you can connect car head unit to the mobile phone (instrument panel - either on the gloves compartment or by making a hole to the small compartment beneath the air condition climatic control - this is actually very easy);
5. Assemble everything back and start the unit;
6. Connect the USB-C to the Mate 10 Pro (or any other mobile phone with USB-C connector) and voila! You'll have the complete screen on the radio car unit.
You also need to install onto your phone the Android app from Kenwood (that will open the MHL/HDMI).
What you can't do on the DNX525:
1. you can't control the phone through the radio unit - you have to use the phone to control it!
Let's say you have a Note4 and a Huawei Mate 10 Pro - YOU CAN NOT use both of them at the same time! Only one!
Everything is related to VW Golf (5, 6, Plus).
Apologies, I had no time for taking pictures .

USB-C hub for Razer Phone 2?

Looking to find a USB hub for my phone. I see a ton of them online, and some of them even kinda say they work with phones. But I know not all of them do. Looking for one that can output HDMI and has at least one USB-A input (two would be nice, but not a deal breaker). I do realize it'll probably require PD input, that's not a problem. [email protected] would be my preference too as a minimum. The goal is to use my phone as a portable gaming device, so I'm hoping to have low input lag for the wired controller.
My hope is somebody has found a decent one that they've tried with this phone and works. Would also accept testimony from people who have tried it on the V30, or any other flagship USB-C Android phone that isn't Samsung (they use DeX, I need no feedback on that).
So... Anybody got any personal experience to share on this topic? Realize it's kind of a tall order, but I'm hoping somebody has found one that works and is reasonably priced.

I too would like to know this if anyone has some info on it. At the moment i have tried 2 different docks, the Alogic USB-C Dock Plus which is just plain **** to say the least, if you connect the charger and HDMI it will eventually crash the systemui freezing you completely. The other dock i have tried is a Satechi Slim Multi_Port Adapter which works to HDMI but does'nt charge the device at all even though it has a charger slot for it & chargers my other phones fine plugged in via the same cable.

MS Display Dock
I have used a Microsoft Display Dock, has 2 USB A-Ports, HDMI, DisplayPort, & charges simultaneously. The Razer Phone work fine with it (TESTED), but honestly the phone seems to be capable of being compatible with any Hub save the ones for the Nintendo Switch. Being that the Microsoft Display Dock is discontinued & old, you can probably find good bargains from 30$ or more. While it is name brand and, from personal experience, its a well built piece of tech, you might want to consider how you plan to listen to your device, and think about adapters with Aux-out if you plan to used wired headphones.

I was goofing around at work and we have these USB c travel adapters that have a USB, HDMI, Ethernet, and vga out, but can't charge at the came time. Upon further goofing around I plugged in Dell WD15 dock, bingo, full output on everything. Comes with a charger so it charges, Ethernet, display port, vga, USB ports. They run about 130 on Amazon right now. Plugged in our projector to it, then some external speakers, Bluetooth my gamepad to it. Loaded my some emulators and I was playing Mario kart while taking some support calls.

Question USB C to 3,5mm Jack - Which one actually works?

Ok, I've ordered two USB-C to 3,5mm Jack adapters from Amazon and so far, both of them failed to function. First one was a UGreen which just wasn't up to spec, my bad.
The second Ugreen I bought (which specifically mentions the S21 Ultra) plugs in, but all it does is create a notification about charging the device. No audio output whatsoever.
So guys, help me out. Which USB-C to 3,5mm Jack actually works with the S21 Ultra?

I bought this one off Amazon, works fine!
UsbC to jack

Oh wow, I found out a way to make it work.
1. Open Samsung Members app
2. Support
3. Interactive support
4. USB devices
5. Choose headphones
6. Plug it in.
7. It will prompt for a reboot.
8. Disconnect the dongle
9. Plug it in again
10. Succes!

I bought this dongle from Amazon and it worked just by plugging it in. I did very little research before I bought it. Don't know if it made any difference, but I concentrated on finding one with the most recent Realtek DAC chip available. This one has the 32bit/384KHz Realtek ALC4050 DAC. Most of the other dongles I found with Realtek chips had the ALC4042 DAC. So, my only criteria was that the 050 was newer than the 042. I'm in the market for a second dongle, so if someone has a better criteria or dongle to recommend, I will consider it for my second dongle purchase. I've also been looking for an "adapter" rather than a "dongle" that I can keep connected to my headphone jack, but I have not found one. I'm looking for something that "looks like" this mic adapter.

I still use the dongle from google have multiple from my old pixel devices and I bought one separately,

The Samsung one does...
