USB sound card works on A500 but poorly so far

I ran Usb Audio Tester root (free) from the Play Store on my Ionian A500 running Civato’s Flexreaper extreme and v6 bootloader . Plugged in my Logitech G35 usb headset and after fiddling with the controls managed to get sound and mike working on the headset. Alas the sound was very poor and the mike was always on . Also the speakers and mike on the tablet were active also. maybe a different usb sound card would work better with this program. At least it shows the tablet is capable of outputing USB sound.
I will keep digging for program or controls to make this work

Yeah me too

[Q] Is there is a ROM or kernel with FULL USB Audio Support?

I would love to use USB Audio on the Nexus 10 such that I can use it when it is playing music from google play music, or locally through the stock music player, NOT through USB Audio Recorder Pro.
I have a Nexus 10 and a Verizon Note 2, both stock unrooted, and it's frustrating because the only way I can enjoy USB Audio on those is with USB Audio Recorder Pro.
Since my Verizon Note 2 is from work, that leaves my Nexus 10 which I could root, unlock, and load a recovery and a ROM (well I have a touchpad with 4.2.2 rom, but I can't even get the device to recognize that a USB audio device is plugged in, but I really want this on my Nexus 10). Is there a ROM right now (or a kernel that I use with the stock ROM) that has full support of USB Audio so any DAC I plug in via USB (With USB OTG cable, of course) will work for any audio coming from the Nexus 10, not just using that USB Audio Recorder Pro app?
Thanks!

I remember this coming up all the time on the Galaxy nexus as well. A couple kernels added full support on their end for all the modules required to use a USB DAC, however the ROM side of things also needs to have special parts included to make it work and I dont think anyone really figured out how to do that or every ROM dev simply didnt want to. So most likely you will always be stuck using whatever app you use to make it work.

[Q] Audio over USB with Android 5.0

I know there have been threads in the past about the Nexus 4 not being able to support outputting audio over USB, but now that stock Android 5.0 supports it, can the Nexus 4 do it?
I'm using the factory 5.0 images and I have an external DAC/amp that I want to use (Fiio e18) that's made for Android, but nothing seems to happen when I hook it up. I've read posts that the Nexus 4 physically can't output power over it's USB, which is fine because the DAC has it's own battery source... but can it at least output the audio?
I started with the stock kernel, but also tried the latest Franco kernel (r214) with no luck. Also, I verified the DAC itself works by using it with my laptop. I'm hoping there's just some hidden setting or patch I need to apply to get it to work... Has anyone else tried this yet?

pls report your findings if you can make it happened!!
i can not help you with your problem but it is something that interest me too. i only can suggest to use a more feature enabled kernel like unleashed or hells core
pls report your findings if you make it work mate!

That's a good idea... unfortunately no dice with the latest unleashed kernel either (98u). It claims it supports USB OTG, so I was hoping that would be enough, but maybe there's more that needs to be done.

one thing that you might not know. nexus 4 does support usb otg BUT cannot provide electricity via usb. you must use a y cable and provide external power so you it might not be possible to use your DAC!

Thanks, I did know that, but I figured that since my DAC is self-powered (it has its own battery) that I wouldn't need to do the y-cable trick.
Worth a try though, I'm going to order one and see if I can at least get regular USB OTG to work. Maybe once that's working it'll be easier to troubleshoot the audio.

Just wanted to update, I got the Y OTG cable so I could have external power at the same time... but still doesn't work. This is with stock 5.0.1 and unleashed 98u kernel. I went into Synapse and enabled the OTG setting as well. DAC doesn't get recognized, and I tried a few free apps that are supposed to do OTG checks, but they all came back that nothing is attached.

Usb otg is one thing and uab audio out is another. USB otg means that you can connect an USB stick or external hdd to your phone ( with or without external power) USB AUDIO OUT need special circuits from your internal Dac to the USB. If those are not implemented you will never have USB audio out. This is something witch depends on the manufacturer ( S4 mini with snapdragon 400 don't work with USB otg or USB audio out, htc mini 2 M8 works perfectly with fiio E18 as a audio surce for external DAC). So if you really need USB audio out please next time do your homework and read before buying a phone. P.S. Htc mini 2 M8 has the best audio ever and really you don't need an external dac. If you need more power just use your fiio as an amplifier with your phone.
Maybe you could find for your phone a apecial kernel modified for better audio experience. Flash that and use your headphones.
Good luck!

Thanks, yeah I don't need usb audio out... I've had the phone for over 2 years and I still really like it, so no plans on getting a new one just for this.
I believe it's physically possible to do audio out on the N4... I've seen random posts about people getting it to work, but they've all been on custom ROM's based on 4.4.x stuff. I'd really rather not try to reproduce that since 5.0 is running so much better on my phone, and I was just hoping with the new native Android support it might work out of the box. But alas, it looks like google locked down 5.0 on the N4 - even USB OTG storage doesn't work unless you put a custom kernel like unleashed on.
In the meantime, I've just been using it as a headphone amp like you suggest and it's a big improvement.

[Q]

Hi, 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.

USB-C audio in 9.0 update

Hello y'all,
I recently discovered by accident that when I tried plugging in my PS4 controller through the USB-C port the phone was showing headphones icon in the status bar. And sure enough, the audio wasn't coming from the phone. So can anyone test this out since I don't have any USB-C headphones, but I always wanted them.
Thanks to anyone participating in this test.
Write your results here.

Audio through USB-C works at least since Android 8.1. I've USB-C mini DAC (Hidizs Sonata HD) and works perfectly. Also I tested Nobsound NS-10g USB input via USB host adapter and also works. So, isn't a new feature of 9.0 update, if you are thinking so.

I've been using fulla schiit 2, usb audio works on 8.1

Actually yes, I was thinking it's new because when I tried my friends USB C headphones it didn't respond.
But thank you for clarifying me! Your response is appreciated.

Does your Hidizs Sonata work also with Android Pie? I've just got Sonata II and it works only if I connect it within one minute after reboot. After that the phone ignores it and acts like nothing has been connected (but the phone is powering the dongle as I see increased draw in logcat and hear a very faint click in the headphones). So if I want to listen via Sonata, I must connect it first and reboot the phone, then it works perfectly. I tried all the available firmwares for Sonata, it does the same with all of them. With the PC or Huawei phone it works whenever I connect the dongle, so it most probably isn't faulty USB DAC, but rather something in the phone. Also I'm missing the option "Audio source" in the USB options in the phone's settings completely, if it makes any difference/sense.

Yes, my unit works perfectly with Android Pie, stock and custom ROM. What build are you using? Maybe something is corrupt

I'm no stock Android Pie, tried the adapter with February patch. Unfortunately adapter just stopped working with all of my devices (got really hot and then died completely), so can't verify with March update.
I'm going to visit an Apple store and try their USB-C - 3.5mm adapter, it is being said to be of a very high quality and is just 10USD/EUR and available locally, so I don't have to wait more than a month for delivery of another Hidizs from China.

Apple dongle behaves the same. Working when connected within ~1 minute after reboot, won't work on later (re)connection. I tried a different kernel to no avail. Would love to know why is it happening.
Edit: it happens that I'm forgetful, see explanation below

Oh my.. I'm stupid guys, I totally forgot that I configured recommended workaround "disable USB host" for 70000.USB wakelock couple of months ago. It was running one minute after boot via Tasker, no wonders I was experiencing this. Dongle works completely fine now (except of volume buttons on the Apple DAC). Sorry for stupid confusion.
