VIM Edge2 USB sound card

According to your suggestion, I am using ubuntu 22.04 desktop on Edge2. The Mali GPU is working great. However, we encountered another problem. We pluged in a USB sound card. Using

alpay -l
aplay -D plughw:4,0 test.wav

we can found the device and play the test file. But when we changed to the system setting, we just can’t find the USB sound card device and let it be the default sound player. Any suggestions would be really appreciated.

Hello @tang1566

Please try the steps below:

$ wget -O /tmp/
$ sudo mv /etc/pulse/ /etc/pulse/
$ sudo cp /tmp/ /etc/pulse/
$ sudo reboot

After reboot, check the USB sound card again.

Thank you! It works!
