No sound from speakers using Chromebook

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.

1. Use aplay -l to see your playback hardware devices.

2. You should see your device sound card, according to your notebook, look for the one that looks like (Make sure that it refers to analog output):

   card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]

3. Make a new configuration file: sudo gedit /etc/asound.conf

4. Put the following and save the file:

   defaults.pcm.card 0 # Replace with your card number
   defaults.pcm.device 0 # Replace with your device number

5. Reboot your computer.
