Am having issues with audio usb, is there anyone else using Cm12 with USB audio (specifically USB DACs)? The problem is twofold:
Poor audio quality. Not even sure how this is happening, since i am using FLACs and a DAC - but audio quality is MUCH poorer/more staticy than same file/DAC combo on any other device.
Sudden dissapearance of USB DAC. At random times, and suddenly the phone will behave as if the USB DAC has been unplugged (or if i had ticked the "do not output sound via USB" option). I have to unplug and replug the device and then it will output sound via the device again. DEpending on the player and options wihtin the player the music would either stop or continue playing via speaker prior to replug.
I realise that "this is only a nightly" and so on. But I've been basically saying USB DAC is an issue since the first publicly available CM12 builds (even prior to nightlies) and the situation has not improved much.
Now...according to this androidheadlines article CM12 official release is coming up in few weeks and i am yet to see any commits towards fixing audio USB issues. I don't mind waiting, but I am afraid that either there is something wrong with my USB DAC (works fine on other devices) or that the fix will not come in time for public CM12 release.

My wired headset has never worked like in Windows Mobile. Polaris just refuses to play music through it. I think developers are working on this, but some users have found workarounds that work.
I created this topic to keep track of this issue in order to give it the importance I think it has. I hope you think the same.
I also agree that this issue deserves more attention from the developers, especially because, at least for me, is the main inconvenience with Froyo at the moment (this and the related issue with usb mounting and adb).
I can confirm that one workaround is to plug either the headset or usb in recovery mode and then quitting into android, after that it works as normal until the next reboot, in the sense that if you unplug and replug the headset / usb it will recognize it. I don't know if it will be hard to fix, but it seems that android cannot communicate with the usb port after fully booting.
Same problem here. The recovery mode workaround does recognize USB but it would not recognize my wired headset.
The working around for the wired headset RC W100
The headset is working with Incubus RLS12 only when you unplug the headset it isn't directly play on the phone speaker.
You have to stop playing (pause) and turn off (end key) the screen. Unlock the screen and start playing with the music on the phone speaker.
It isn't necessary to reboot with the headset connected to enable it.
Hi!
I can't get my wired headset to play music through it. Unless I've not understand the workaround it does not work for me. Here is what I've done:
- stopped the music player (while playing through phone speaker);
- switched off the display;
- connected the wired headset;
- start playin' again but it plays always through phone speaker;
Thank u.
I can confirm this issue.
I really love the work done with Android, but I can't use it as an MP3 player, because my wired headset doesn't work.
Is this known with the developers, and being looked in to?
Nothing new on this issue so far?
Up!
I am still ionterested in this issue!
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.
Hi all.
I have the Xperia Tablet S. I know it is a 2012/2013 device but I ran into an issue with the sound.
When I first did the setup walk through, all clicks and system sounds routed correctly through the built in audio. In fact, after about 10 minutes of being in the OS audio still worked correctly. After that, the audio seems to jump between "Headphones with Mic" and "Internal Speaker". My Mic obviously is cut off as well when it thinks there are headphones plugged in). It did this before I ever plugged headphones in.
I have been all over the web and this site seeing very similar issues with no REAL solution.
I have installed the Sound About newest BETA thanks to many of the posts in this forum because it shows me live where the audio is being sent. I can sit and watch it switch back and forth roughly 10-20 seconds sometimes quicker. It does know when I plug in a set of headphones and when I unplug but it wont keep one or the other permanently (unless it is headphones actually plugged in).
My main question is this.. Is it software of hardware? Obviously the tablet thinks there is something plugged into the headphone jack...sometimes. But it can work correctly as well sometimes. Just not for very long.
I can set Sound About to route everything all the time to the internal speakers but then that means every time I plug in headphones I have to turn off the app for it to work right.
-I have tried Sound About (works, but annoying to switch back and forth)
-Tried inserting and unplugging headphones in (and very slightly turning and wiggling the jack to see if it was a loose connection).
Again I have the Sony Xperia Tablet S running 4.1.1. (perhaps it is Jelly Bean bug). If thats the case ill deal with using Sound About.
Everyone here has always been awesome. I know far less about android than other OS's so I feel a bit more helpless. I just want to enjoy music and videos.
USB Audio Pro says 'USB Audio device initialised' but App USB Host check says can't find USB Host??
Went on one plus chat just before buying op6 but wouldn't commit to saying if it had or had not got USB Host! Have OP3T which works OK with my Audioquest Black DAC.
Have connected the DAC to op6 and it plays thru USB audio Pro, but it doesn't sound great. Streaming Tidal & Spotify directly produces heavy glitching esp at start of tracks, and again doesn't sound great. . No glitching thru headphone socket. Have been in touch with Audioquest and they seem to think one plus android version of op6 is switching USB off
So wondering if USB Host is supported, or what others experience has been ?
Any update? Did you managed to fix the issue? I am planning to get Audioquest
The phone (running the latest 13-beta and rooted) just can't tolerate USB-C wired ear pods. Audio drops out after a few seconds--even tho the app shows it's still 'playing'. Sometimes I have to stop the app, un-plug and re-plug the pods to get it to play in the first place. The notification area will show that wired headset is attached, but audio just won't stay on.
This morning the phone locked-up while trying to get them to work and I had to hard-reboot.
This happens with a brand-new pair that had a native USB-C connector, and an older pair I'm using with a USBC-to-miniplug adapter.
My bluetooth OnePlus pods work reliably every single time. Tried with two different audio apps, still no love.
Any thoughts?
Do you have File Share as Standart on USB Connection?

Wow. You might be on to something! Under USB Preferences, "USB controlled by "Connected device" is selected and "Use USB for File transfer / Android Auto is selected--but greyed-out so I can't change it. Am I missing another setting or something...?
I Heard about this Problem before. But i think IT got fixed in latest stable Firmware....

Would some of you smarter people please help figure out what's going on? I/you can then file a bug report which won't result in it being closed due to their misunderstanding. The primary issue is that music stops playback when a USB-C adapter...
