Hi @tmigone , sorry for the late reply

this is cat /proc/asound/cards output in the host OS:

root@a38b613:~# cat /proc/asound/cards
 0 [Audio          ]: HdmiLpeAudio - Intel HDMI/DP LPE Audio
                      Intel HDMI/DP LPE Audio
 1 [Device         ]: USB-Audio - C-Media USB Audio Device
                      C-Media USB Audio Device at usb-0000:00:14.0-3, full speed
 2 [bytchtnocodec  ]: bytcht-nocodec - bytcht-nocodec
                      AAEON-UP_CHT01-V1.0-UP_CHT01

then I create a container like suggested and this is the results:

I also execute cat /proc/asound/cards in the hostOS:

root@a38b613:~# cat /proc/asound/cards
 0 [Audio          ]: HdmiLpeAudio - Intel HDMI/DP LPE Audio

                      AAEON-UP_CHT01-V1.0-UP_CHT01
