I've tried to use several USB sound adapters shared from my Raspberry Pi 3 VirtualHere server from within a Linux VM without success. From Windows, they all work fine. In the Linux VM, this is what dmesg is giving me when I attach the sound device:

On the server, when I plug in the device:
[12277.988176] usb 1-1.4: new full-speed USB device number 9 using dwc_otg[12278.091062] usb 1-1.4: New USB device found, idVendor=0d8c, idProduct=000e, bcdDevice= 1.00[12278.091101] usb 1-1.4: New USB device strings: Mfr=0, Product=1, SerialNumber=0[12278.091124] usb 1-1.4: Product: Generic USB Audio Device
On the server, when I attach the device to the Linux VM:
[12344.872223] usb 1-1.4: reset full-speed USB device number 9 using dwc_otg
Server and client use the latest version 5.6.0. Other devices work just fine. Anything I can do to further diagnose or fix it?
Cheers,

Sound support is a bit patchy on linux.
What kernel are you running inside the vm?
uname -a
It really needs to be in the 6.x for the best chance of working.
.
$ uname -aLinux 6.2.0-31-generic #31~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Aug 16 13:45:26 UTC 2 x86_64 x86_64 x86_64 GNU/LinuxFunny thing is, I am positive that this was working several months ago on the same machine. BTW after a reboot, it is still not working but dmesg has changed somewhat:

Those messages "not implemented" etc... are all OK and shouldn't affect the sound pass-through.
What software are you using to listen to the sound? What is it actually doing....does it make any sound or is it silence?
.
The device is not being fully registered and the dummy sound output keeps being used. The audio mixer shows only the dummy sound device in the "Virtual Output Devices" section but the "Hardware Output Devices" section stays empty. To test, I play a video in the browser and it is completely silent.
.
Ok i dont know the problem.
I do notice that my ubuntu is
Linux ubuntu 6.5.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Mar 12 10:22:43 UTC 2 x86_64 x86_64 x86_64 GNU/LinuxIt might be worth updating the kernel on ubuntu to see if it helps
.
Upgraded the kernel to 6.5 but no change. Oh, well, will look into a workaround, using xrdp for audio forwarding.
