Sound problem - No sound on Zorin 15.3

Ok an alternative. Have a look at Alsamixer (run from terminal) and see if specific sound channels are muted "M" or maybe not showing. See this post:

Internal microphone not working on new install

Go into terminal and type Alsamixer The Alsamixer sound settings window will then appear showing sliders for your sound inputs and outputs. Check that your mic (inputs) settings that appear to the right of the speakers etc (outputs) sliders are not set muted [M]. You can unmute and increase the input volume levels. You can then save those settings using sudo alsactl store
