Re: USB DAC detected and looks like there is a output but not sound

Same problem with my walkman.

5.10 works fine, def something with the new kernel, tested in a fresh install.

Kinda new, how can I report the bug?

Now that the default card is set, could you post the output again of:

killall pulseaudio
speaker-test -c 2

This time I am under 5.11.6-arch1-1. Hope this update can fix my issue. However, my issue is still not fixed.

killall pulseaudio

My USB device didn't show it received any signal but KDE Audio component shows dynamic on the sound meter while playing music.

If I have time. I may try to trace diff between kernel 5.10 and 5.11 to find what change leads to my issue.

Would you mind show some details of your issue? Like what model of the DAC. How you fix your low voltage issue

Sorry for not being able to help you. I am not using WALKMAN or any SONY DAC, and I am using a USB hub that can be connected to an external power supply (which forgot to connect at the first time)
