There is not much info on SIS sound cards - do you really have one?
Run lspci (in a terminal) and check - you could post it here between code brackets
You could also try
- Code: Select all
echo options snd-hda-sis model=ref — sudo tee -a /etc/modprobe.d/alsabase
or change sis for intel
alsaconf is about as depreciated as ISA sound cards
