no sound on vpceb17fx sony trusty (upgrade from precise)

Asked by aminorex

I have no speakers. Devices are not detected in pavucontrol although alsa-info.sh shows them:
http://www.alsa-project.org/db/?f=9aefb815296c546f9d4710097ea51bbd1519c2d6

How can I make progress in diagnosing this?

Your Terminal output shows this issue:

Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 64
  Mono: Playback 0 [0%] [-64.00dB] [on]

Master channel is at 0% volume....

Please run alsamixer in a Terminal and then increase volume to 100% on the "Master" mixer channel....

Then retest sound output on headphones and analog speakers.

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

Can you help with this problem?
