I have a Shanling UA1 Pro DAC which I have been using for about 1 year on Ubuntu 22.04 without any problems. The sound was working fine until one day I updated my system and the sound stopped working.
The DAC is listed in my audio devices. Pulse audio is working fine and there seems to be no error messages.
I have tried reinstalling pulse-audio and I have tried other USB DAC's which work OOTB.
This problem seems to have happened once I upgraded my Ubuntu Installation. I have also tried this DAC on another computer using my Thinkpad P16S and it will not work either which also has an installation of Ubuntu 22.04.3. Yet when I tried this same DAC with my Windows 11 PC it works without problems. I have also tried it on my M1 MacBook Air without any problems.
Does anyone know what could be causing this error?
