Are you using HDMI audio?

analog to external speakers 3.5 mm jack. This machine has only one set of audio output jacks on motherboard. Using known good speakers (gigaware)

Your Terminal output shows several muted channels in alsamixer (including the Surround, Center,LFE and Line channels)

Please run alsamixer in a Terminal.

Please use alsamixer to unmute (using M key) and increase volume to 100% on ALL channels, including the Surround, Center,LFE and Line channels.

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

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