Hi everyone,
I'm having this weird problem where i connect a usb-c device (Electronic piano in this case , Yamaha E737) - The sound is disabled on the tablet. No matter what app i use, there is just no sound, even when trying to connect earphones - no sound.
I tried using an advice from this forum - Going into developer mode and disabling some kind of USB auto sound routing - but this didnt help either.
Help would be much appreciated.

Hi guys I was wondering if it was possible to get the transformer to output music through the USB ports. I have a set of portable Creative speakers which have great sound and would love to use them with the transformer. They are powered and receive audio from USB
It is very possible, but you'd ave to add the device modules (drivers for the device) to the kernel yourself because it isn't native. I've been trying to get USB headphones working for a while.. :/

Got work usb audio on tf101 with CM10. Just kernel modules for usb audio are not enough to get sound from apps to be routed through the DAC. It's also needed to patch vertana audio driver.
I know it's been a long time but I just got around to rooting my TF101 and actually enjoying it. Has anyone done anything similar with speakers or headphones

Lollipop - Any Improvements?
Has anyone been able to get USB Audio working in a Lollipop ROM given the improvements to USB host?
So far, no luck for me:
KatKiss Lollipop 5.1 #21 ROM
JBL Pebbles USB Speakers connected to the dock
My tablet recognizes there is a USB audio device as the audio stops after connecting.
Also, disabling auto routing of audio to USB audio devices does what it supposed to do - so detection works.
Connecting the headphones out to the aux in of the USB speaker didn't work. Tablet speakers shut off but no sound in the USB speakers.
I could get it to work is powering the speakers from an AC charger and using the tablet headphone out to it.
Also, USB Audio Tester app works in that it can detect the USB device and it was able to play audio out of it (tested via connecting int mic to ext speaker mode and raising the volume bars).
To my understanding from the developer's description, that app uses non-standard interface to output USB audio.
The speakers work fine on Windows and Chrome OS without drivers so I was hoping it was plug and play.
Update:
I did note that I had to raise the in-app playback control volume bars first though to work in USB Audio Tester app.
Also, when connected to a computer and using the Aux In of the speakers, my phones and tablet can play audio.
Based on power draw of a USB charger I connected, the speakers use 0.6W idle and about 1W max.
Therefore, I'm thinking maybe it fails the USB enumeration in Android and the default 100mA is not enough.
Anyone know how to check the USB host enumeration settings?

Since we are talking about USB HOST, maybe it's important to use USB OTG cable, I reckon, as not all USB cables are equal. This has just recently struck me, because I used USB cable that came with my soundcard the other day. Its of great quality, sure, but I'm almost positive it's not OTG. My audiocard is externally powered, so on the other hand it might be just unimportant in my case...
USB Speakers of all sorts have generic DACs in them that require no special drivers and have to work out of the box on any system as long as USB connection and standard USB functionality are intact. Success stories of USB Audio working under Lollipop are rather abundant.
If USB Audio Tester works for you then USB Audio Player PRO should too, those are made by the same guys AFAICT. UAPP is no free app though, costs a sum, and sadly its proprietary driver(yeah, those devs apps use "non-standard interface") only works inside the program, one cannot watch Youtube or MX Player by using that... Compatibility list is on the devs site. My card, E-MU 0404 USB is listed as compatible for only RECORDING, not playback. Heck, I'm absolutely certain, I saw someone on some forum claiming they got same card totally working under UAPP and that wasn't even on Lollipop! Anyway, my trial and error continues...
I don't have a USB OTG cable for the TF101.
Instead, I'm using the keyboard dock that provides two USB ports.
It should be the same thing.
It is very good to hear that USB audio is working for a lot of people on Lollipop.
I've tried testing my speakers on more Android devices - my Nexus 5 and Samsung Galaxy Tab S.
Like the TF101, the speakers are detected as the OS switches over (no more audio out of built in speakers) but no sound out of the speakers themselves.
I'm leaning towards these speakers are not compatible with Android yet.
Sigh - non-standard standards.
This is actually incredible. Before upgrading to Lollipop on Galaxy S5 I was able to plug my DAC (a Dragonfly 1.2) via USB OTG cable into my Galaxy S5 and enjoy pristine usb audio without a single hint of a problem - all apps working - MX Player, Inbuilt Music App, Poweramp etc - all working perfectly.
Then I upgrade to Lollipop, which is supposed to be great for USB Audio, and it doesn't work any more. At all. I am now back to using an app called USB Audio Player Pro, which allows you to use DAC audio devices to connect to headphones and (thank god!) this still works awesomely, but I was really enjoying all my apps making use of my USB audio device and now that has just been screwed over by the update.
There was so much pleasure in just plugging in a usb audio device into the phone via an OTG cable and everything working great, but now I just fall on my knees and shake my fists in the air bellowing "WWWHHHHYYYYYYY??!!!!"
Has this affected anyone else ? I've restarted, factory reset since the update and googled the crap outta this and all I can find are people saying "Yay! USB Audio functionality has been added with Lollipop".
From my perspective, this appears to be balls.
I'll happily downgrade back to the older android OS if its possible just to get this one happy function back.
Hi I think you should ask your question here instead. There are lots of active people in that forum that will give you some answers and hopefully a solution.
thank you and good luck
Hi Guys!
I have just got my Galaxy S6 a couple of days ago and i have hit a bit of a problem.
In my car I have an ibolt cable that connects to the charger and aux input of the car and the micro usb port of the phone.
With this I get both charging and audio with one cable.
This worked flawlessly with my S4, I only had to go to accessories -> Dock settings and enable audio out through micro usb. (that was on kitkat)
Now with the S6 running lollipop there is no such settings, I have understood that lollipop supports it because in developer options there is a box for: Prevent usb audio routing, But that is unchecked.
I have tried som apps from play store but none of them have worked and the sound only goes through the phone speaker (Though it enables dock mode when i connect the cable)
I have also been in contact with the swedish Samsung support center but that is another funny story, resulting in me only getting more frustrated
So does anyone knows if this problem is solvable?
Hi there,
You'd be best served asking for help from the experts who own your device here:

Hey,
I'm using a Lenovo Tab 3 in my car as a basis to play audio from as the standard interface of the car is terrible. I have it set up so that the tablet is plugged into the car radio USB for power, an app ensures it comes on / turns off (standby) in accordance with the power state. I like my audio quality to be as high as possible but find myself forced to use bluetooth or AUX at the moment because I cant figure out if there is a way to stream via the USB.
The car can read a song from the tablet when connected, but the navigation of files is via the car radio which is not what I'm after. Is there a way to use the USB almost as an AUX, where the music is selected via the tablet but not processed by the tablet and instead sent "pure" to the radio?
I'm getting a fair bit of distortion through the bluetooth so unfortunately it isn't really the solution here. The audio is also getting processed twice, by the tablet and the car which will reduce quality.
Any help would be greatly appreciated. I'm not against rooting, although the tablet hasn't currently been.

To my knowledge, streaming audio via USB isn't possible, I could be wrong though. You can play music from USB as if your device were a USB flash drive.
Here's some info on android USB audio.

Thanks for the reply,
I feared this may be the case. I think a DAC is going to have to be the way forward with this unfortunately!
Hi All,
I've just received the JBL Reflect Aware C earphones, which only have a USB C connector.
I've plugged into my Mate 9 (MHA-L29C567B190), and it recognizes as 'Reverse Charging - Charge the other connected device'.
Even though the phone doesn't show any message of a headset being connected, All multimedia apps are working ok (sound & voice), such as skype, whatsapp, google play, etc.. but whenever I try making a phone call, the phone just acts as no headset was connected.
Also tried using SoundAbout, and 2 different phone dialers (Zero and TrueCaller), but so far nothing works.
Also tried the same earphones in a Samsung S8 (same problem).. and in a Xiaomi phone, which worked perfectly fine for phone calls.
I know there are already some threads about this topic, but all of them talk about DAC options, and couldn't find any talking about USB C earphones.
Has anyone tried it ?
THANKS !!!
Ricky.
Anyone ? - Thanks!!!
Having same issue with Pixel and Essential USB-C HD earphones.
