The usbaudio from rom1v

Not working (Pipe error)

$ usbaudio
[INFO] Device: [2833:0083] XXXXXXXXXXXX
[ERROR] Pipe error
[ERROR] Could not get AOA protocol version
[ERROR] Could not forward audio

My setup:
Kubuntu 19.04 x86_64

Tried running before and after running scrcpy, but I get the same error. scrcpy runs fine.
Also tried as root, but same error.

Any help? Thanks!

EDIT: forgot to say that I'm using a Oculus Quest

[ERROR] Could not find matching PulseAudio input source

I use Realme 5i and Android 10. The device is detected and audio forwarding is enabled, but i just can't find the input source.

Any plans to support PipeWire

A lot of distributions are ditching PulseAudio for pipewire. Any plans to support it?

[ERROR] Could not initialize AOA

I am using Debian from Microsoft Store.
Followed the steps on the guide completely.
As i execute "usbaudio" it shows the error

[ERROR] Could not initialize AOA

I have this error in ubuntu with PulseAudio maybe you can help me with this. Thanks.

Uninstall usbaudio

Hello!
What is the correct way to uninstall usbaudio? Just by deleting the folder?
Thank you!

Setting adb executable path

I'm on Ubuntu 18.04 LTS, using the adb from android sdk's (from android studio) for scrcyp lauching setting the adb variable to my custom path but that doesn't work with usbauio:

ADB="/home/matheus/bin/adb" usbaudio
[ERROR] Could not find device

Thats the only message I get... even thought I have it:

adb devices
List of devices attached
192.168.0.113:5555 device

And scrcpy is working. That should be a feature or maybe I didn't just found it out yet..

Need a feature to forward audio without using USB cables. Instead prefering wifi

Plugging in and out usb cables are very annoying.
Is there a wireless feature available in USBAudio?
If not kindly setup one.
if yes help me to configure

Not working, need some help

I want to record my mobile gamplay with sound using scrcpy and usbaudio, the video is okay but there is no sound.
The terminal output of usbaudio is like this.
Can u help me pls.

Does It Support Windows

Android 9+

Does it work on that version or does something else have to be made?

Audio device gets recreated on every USB connection

Even if usbaudio is not running or anything, now an audio device is created on my system everytime I plug in my phone. Audio gets forwarded to here as normal, but I'd expect it to not create the device when not asked, just when using usbaudio. Well, I find some cases where it'd be convenient to just use this, but I also want to know a way to make this not happen.

This happens even after reboots.
