I am struggling since days to get Ubuntu to recognize my audio card. It looks like the hardware is detected (Intel C230 on motherboard), but can not get it working. My laptop is a Acer V5-591. I have "dummy output" as hardware. I run Ubuntu 20.04 with kernel 5.8.0-50-generic.
I have tried alsa and oss4.
Based on the diagnotic steps (https://help.ubuntu.com/community/SoundTroubleshootingProcedure) , it looks like alsa is not recognizing with audio card. Here is the output of alsa-info.
Cheers Marc
