[Q] Unable to play music in my car stereo with USB cable

Hi
I am unable to play music in my car stereo via the USB cable. It says that mass storage mode will onlly work with memory card
All the reasons why Android was so much better than iOS seem to be fading away one by one. I miss GingerBread.
Other than using the headphone jack RCA to RCA cable, is there any way I can use the USB to play music? What is this MTP and who supports it??
Oh, and my car stereo doesn't have Bluetooth capability, hence the question.
Thanks.
Farhad.

The MTP USB protocol was designed to solve the problem of allowing both the device and the USB host to have access to the file system at the same time. Unlike USB Mass Storage (where the support comes from drivers in the OS), MTP typically has to be integrated into the applications that communicate with the device. Since widespread MTP use parallels KitKat adoption, you're unlikely to see support in any automotive head unit that's more than a year old. And given the time needed to develop, test, and certify automotive electronics, it may still be a year or more before it becomes a common head unit feature.
Using the headphone jack and controlling playback from the phone is one viable work-around. The other is to just throw all your tunes on a cheap USB stick. It's a little bit of a hassle to keep two devices synced with your music library if it changes often, but your options are pretty limited.

Anyway to play music thru usb port on car radio?

I'm wondering if it's possible to play music on a car radio (or any usb input) thru the usb port on the note 4?
Any app, mod, hack, tweak to mount a certain folder (music) as a thumb drive?
I have several usb input audio devices, but I can't access anything when I attach the note.

I feel you, I tried to do the same with no success ended up buying a 3.5mm headphone jack to rca for my car stereo ?

Yeah that sucks

So you're trying to MOUNT a USB DRIVE filled with music and play it to your car stereo? You using a 3.5mm cable or Bluetooth here?
I have some USB OTG cables (really cheap, ebay) and play the music from my SD card using PowerAmp (FLAC Playback, also allows folder choosing; your USB drive?) through the OTG cable, to my Fiio E07k, then to my headphones/speakers. Works FLAWLESSLY, and if I plug anything to the headphone jack simultaneously, it will re-route the audio.
Hope this helps.

I want to use a usb cable from my phone into my car radio usb port and play the music that is in my phone thru the car radio using the usb cable and not the 3.5mm head phone jack.

i believe this is a feature in lollipop to enable audio through usb. gonna have to wait
"Android 5.0 has added official support for USB audio devices (both input and output) along with lower-latency audio input and the ability to mix up to eight audio channels. All of which means one, amazing, thing: "

I want my phone to act like a usb thumb drive when I connect it to my car radio thru the usb port.

I can't remember, I set it up a long time ago. It's a 64gb uhs1 card. I remember I had to format it with a pc app to get it to be recognized in my (then) Galaxy S3, and I simply moved it in to my note 4.

OK, with that being said, what stereo you using? Display style or single din?
Is it linix based or android?
Brand and model number?

I've got a pioneer single din in the wife's car (can't remember the #) and I've got a Kenwood dnx5120 double din, which has a usb port that will read a usb thumb drive or a hdd (or iPod / iPhone) but will not "see" my phone when connected usb.
I figure if it can read a usb thumb drive or even a hdd, why can't the note 4 mount itself as a thumb drive (external sd card) and allow my radio to read it's content and play it's mp3's?

Ever found a way?
Im in the same situation.
Ive tried the apps that enable usb mass storage mode on my sgh-1337m galaxy s4 and while it works and my computer recognizes my sd card as an usb drive, my car stereo still does not.
Any other way or USM enabler that works?

I have never found a way ? sad to say. If anyone can point us in the right direction if that direction even exists, that would be great.
Sent from my Samsung Note 6

I just bought a Kenwood KDC x701 and I had a very unusual set of circumstances. When I plug in my HTC 10 to either USB cable one or two nothing happens other than charging the phone. The Kenwood radio does not recognize the HTC 10 at all. I thought this was completely normal as I was not trying to mount the HTC 10 internal storage to play music files as I have no music files on my phone except audio recordings I make myself a phone calls and such. I am able to stream music via Bluetooth from the phone to the radio just fine and that's what I've been doing this entire time. The only thing I listen to is tidal music streaming service. So the other day I went to plug in my lgv10 to charge while I was driving and a funny thing happened. The radio display indicated it was reading and then went into a hand mode, it is literally called hand mode LOL. The next thing that happened was a message popped up on my phone asking me if I wanted to download a Kenwood app from the Play Store I hit cancel. Then all of the sudden it started playing music from the Tidal music streaming app. Although no information was displayed on the radio I was able to use the buttons to skip forward and Skip ahead of the different tracks but I am not sure I am able to pause or play music on the radio controls. I am not sure how it is possible to stream digital audio through the USB cable directly into the radio. I have no audio files stored on my phone on either phone and I'm not even sure how to mount internal or external storage on the phone if I wanted to use the head unit to access any audio files. So I called Kenwood and they said what I described is not possible with any of their head units. They did say that I should be able to mount my internal or external storage on my phone and use the Kenwood app two act as a music player and play the files on the phone and have them information sent to the radio. What it sounds to me like is I have a USB OTG situation with the LG V10 and no one knows why. Also of note I am unable to stream music from the lgv10 to the Kenwood stereo and no one knows why Kenwood does not know why. All of the track information is displayed on the radio I can control the songs going backwards and forwards the timer countdown xcetera but there's just no music. I will say streaming music from Tidal music service streaming app sounds much much better through the USB cable versus Bluetooth. I can't believe how much better it sounds over the USB cable it's like adding an amplifier to your system. I will try to make some videos and if this helps anyone that's going to be awesome. Also of note when I select source to USB when I have my lgv10 plugged in it calls the source Android1. This totally sounds to me like USB OTG. What do you all think and has anything like this happened to anyone else? And this does not work with my HTC 10.

I don't believe that this is possible any longer. It was possible under older versions of android (pre kit kat i believe) where the "internal sd" was seen as a physically separate storage device instead of being mounted under /data/media. Once they made this change, they had to swap from USB Mass Storage mode to the annoying Media Transfer Protocol. The reason Mass Storage had to be dropped is because of how it functioned. When you allowed access to your "internal sd" it would have to dismount it from the OS to give the host device plugged into the USB port exclusive access to the file system. Since they made the move to mounting it as /data/media there is no way to give that exclusive access any longer. Trying to dismount that /data/media to give that exclusive control would yank away all of the writable media away from the OS. Android would likely crash, or at least nothing would function any longer.

How to use usb audio?

I want to play music from my phone to my PC speakers through a USB cable connected to the PC. Is this possible? If so, how do I go about setting it up?

Unfortunately the computer is going to recognize your phone as a USB mass storage device so what you are describing isn't possible. It IS possible for you to use a media player on your computer to play the audio files stored on the phone.
USB Audio devices identify themselves as such when being plugged into a host system (Android OS, Windows, or MacOS). USB audio out is working on the Turbo, but what you describe is connecting two hosts to each other.

So is there any software setting I could change to make the turbo appear as an audio device?

Audio out via the USB in car?

Hi
I've received my P20 Pro this week and am loving the phone so far. However, one big issue remains that i can't seem to get my head around - how to play audio from the phone through my non-Bluetooth car stereo?
I previously had an iPhone 6 where this was easy; plug the phone in to the stereo via USB and it would simultaneously charge and play music from the phone through the car stereo.
But when I plug in the P20 Pro via the same USB port, I can't seem to get audio coming out. I know it's possible - as obviously headphones plug in to the same USB-c port - so is there something I have to turn on or toggle to get it to send audio out?
Any help much appreciated. Thanks.

Check you don't have this option enabled in developer options?

Thanks - I looked and it's not checked. In fact, the headphones work when you plug them in, so it is allowing audio out with certain connections.
It's just when I use the charging lead to connect the phone to the car stereo (USB) - nothing happens. It doesn't even charge, and says "check USB" on the front of the stereo. if I play music when it's connected, it just comes out the phone - which obviously it wouldn't do if it was connected to the stereo.
Do I need a specific audio lead, rather than just the basic charging one that comes with it?
Coming from an iPhone background, it's just the same lead... so I'm struggling to see why this won't work either.

My case was huawei p20 pro generate so much noise and jitter during playing through USB audio connect to Helix dsp, it solved by changing USB speed mode from full speed mode to high speed mode on the Helix dsp USB setting. As my iPhone was working fine on both mode. In case if you can try to change setting on your car stereo system. Try to consult with your car stereo manufacturer.

Hi Slangking, did you already find a solution to use P20 (pro) audio over USB in your car? I'm having the same issue as you, went from the iPhone 6 to p20. Just a cheap USB stick works, and I could even remote spotify on my iPhone with my steer trough USB. Changing the USB output in the developer settings to audio source didn't work
- EDITED -
I did some research and mounting your memory card as a USB Mass Storage will work like explained over here, but I still can't find out how this will work for the internal storage...

UPDATE
I found something called WIRELINQ: Smart Android USB Converter Cable for Car Stereo. Started as a kickstarter project, but are now able to buy. Will try that one out.

I got one of these and found I can't get anything to play through the stereo, the audio plays on the phone speakers but the track info displays on the stereo screen and the steering wheel controls also work, I can disable USB audio streaming via the dashlinq app which makes radio player within dashlinq work properly.. but nothing else works.. have you had any luck?

Thanks for your reply. You are a step ahead of me. I have the Wirelinq cable but couldn't get it to work, not even the track info on my cars stereo display. It recognise the Wirelinq cable, but not my phone. I am in contact with GROM and even tried to install a new firmware update (which I was able to install myself by connecting the cable to my computer), so there last message was:
This is issue of the phone USB Audio output in software not working correctly as standardized by Android's AOSP. You will have to contact Huawei to get support and resolve it on phone's software end.

Did you ever get anywhere with this? I'm a new P20 Pro owner (also having switched from iphone 6) and wanting to crack this issue. Thanks.

Not sure if there is a solution. iPhones behave differently when connected to stereos, just like an usb stick. Android devices don't, unfortunately. I am using an AUX cable with the usb-c adapter in my husbands car, or bluetooth streaming in my car.

Bleutooth receiver to AUX

No, it didn't work. Maybe it will if GROM will come out with an update. I've returned my cable and have bought a bluetooth to AUX receiver adapter on eBay for just a few dollar. This actually works very well, you plug the bluetooth adapter in your USB and the cable in your AUX and you can listening wireliss music on each app through bluetooth. The downside is that you won't be able to see your track details, no remote from your steer and the quality is different. But you can still charge you phone with a normal USB cable while listening. It's not a solution, but I got used to it now.

Not a bad idea with the bluetooth to aux!

iphones actually don't behave like a usb stick when connected to a stereo. the music is still played on the iphone, but the sound is streamed to the stereo. controls on the stereo actually control the playback on the iphone itself.
with android, to play audio over usb, you need to use mass storage mode, which will behave just like a usb stick.
ios can output digital audio over it's usb cable, which the stereo can receive.
android can output audio through usb-c, but i don't think that it can be used to output audio over the usb cable like iphones can. it might be some protocol that iphones use and android phones don't, but technically it should be possible.

Just stumbled upon this thread as I am in the same situation. Basically, I have a P20 Pro and a Huawei Mediapad M5 Lite that are behaving exactly the same..i.e they cannot play audio from USB to car stereo's USB ports. The internal media can be browsed and played via car stereos interface but you cannot stream music via USB from phone (say Spotify) to car stereo.
USB audio streaming works if I enabled ANDROID AUTO at the car stereo and installed ANDROID AUTO in the phone/tablet. You might ask why not just settle for this setup?
I can, butI I hate so much the AA's "Swipe to Unlock" lock and the changes in the UI when AA is active.
What I want is the plain/original phone interface (without AA) and all audio routed via USB.
Bluetooth, I know is an option, but again, it would be nice if this (USB) can be solved. It seems possible, I think. If AA can switch USB audio streaming on, can other apps or workaround/reverse engineering not?
BTW, i tried playing with the Developer Options, USB Configuration as "MTP or Audio Source" --- no luck here

Just bought a Kenwood DDX6906S receiver for my 2013 GMC Sierra I cannot get anything to work via USB. USB debugging enabled. I feel like I've been going in circles. any help would be super appreciated, TIA

Any way to stream hdmi source to android auto ?

Hi,
I want to connect my android tv box (XIAOMI MI BOX) to android auto car.
For this purpose, I'm looking for some way to stream video from hdmi, may be using some "HDMI TO USB ADAPTER" or similar device.
Any ideas?
Thanks

Nothing to do with Android Auto, but assuming you have RCA(Yellow) video input, you can get HDMI to RCA converts and just use the aux in. If you really mean using AA, then I'm guessing you'd need to root and try to install AA mirror. I doubt HDMI to USB video would work.
