Your Terminal output shows several muted channels in alsamixer
(including the Headphone and Mic channels)

Please run alsamixer in a Terminal.

Please use alsamixer to unmute (using M key) and increase volume to 100%
on ALL channels.

Also make sure to disable "Auto-mute mode" and to enable "loop-back mixing" in alsamixer.

Then test all audio jacks at the front and the back of your PC.

Please test sound output using both speakers and headphones...
