Hi,
I read somewhere that one of the new features that JB brought to android was the ability to use USB audio devices natively, i.e support for external USB DAC's.
This should enable us to use USB speakers (I'm NOT talking about the ones that draw only power from USB) such as my Arctic P531 for instance.
However when I plug in my headphones to my infinity's dock, the audio still plays from the tablets speakers! I can control the system volume by the volume control on my headphone but audio comes only through the tablets speakers :crying:
Anybody know if i'm doing something wrong? or not doing something?
Has anybody gotten a USB audio device working on their infinity?
BTW, FYI, I am running stock JB, stock bootloader, stock everything.
come on... anybody?? any help?? i cant be the only one here??

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.
I have a sony ps3 wireless headphone,
So basically it has a usb that is connected to either ps3 or pc and then all the sound is transferred to headphone instead of speaker.
there is no driver required on pc, well i guess its built in the usb itself.
Now i want to use this wireless headphone on my GS3,
I first tired on AOKP based cm10 and it didnt work, then i tried on stock Rom(one with touchwiz) and it worked.
I like CM10 and want it to work on that.
Can any one tell me if there is a solution?
Thanks
I want to do WHAT??
I'd like to use my Asus Transformer TF101 (running EOS #89 at this moment) to do sound recordings (mostly interviews / voice) via an external found mixer plugged in via USB. I admit at the outset this may be crazy. But can't hurt to try, eh?
First, yes, the Lexicon Alpha V I have does power up when plugged into the USB ports on my TF101's dock. So far, so good.
But here's as far as I've gotten. So...
What hardware tweaks, providing this is possible, must I make to get the tablet to detect the mixer AS a mixer, and the mic I have plugged into it as a sound input device?
What software will I need to do recording should I succeed in getting the mixer / mic combo recognized?
Other (and there must be other) issues I've not thought of?
Thanks for your help!!
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
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!
