Description

I have a 5.1 surround speaker setup on a Fedora Core 9 system with Intel ICH5 audio. The pulseaudio packages are of version 0.9.10-1.fc9.i386. I get no output on my rear channels, center, and LFE. The audio control (pavucontrol) shows all 6 channels at 100% and unmuted. The volume meter UI (panam -> Devices -> Sink -> Properties) shows signal levels on all 6 channels when I hit 'Play' from 'Sample Cache'. Front left and right work fine. All channels used to work fine earlier when using ALSA directly with surround51.

  • status changed from new to closed
  • resolution set to fixed

Looks like a mixer initialization error, you can fix by playing around with "alsamixer -c0".
