There is no hardware volume control when you use ac3 pass through SPDIF
the volume is controlled by your AC3 digital receiver

you have to turn off IEC958 Default PCM if you are using AC3 passthrough SPDIF

Simple mixer control 'IEC958 Default PCM',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]

Status changed to 'Confirmed' because the bug affects multiple users.

It starts with no audio every time.

Mine is OK now.
