I need help.
I have installed Ubuntu 20.04 on my Toshiba CB35-B3340, no dual booting. I have no sound from my speakers or headphones.
When I go to sound settings, the only output device shown is HDMI/Display port.
When I run alsamixer, I only see S/PDEF, there is no master or headphones, etc.
I have tried many of the suggestions posted without success. I am not too experienced, but will to try. Any suggestions are appreciated.
