"pactl stat" only shows the default channel map, but that has little practical effect, because the device auto-detection will use a channel map that fits the hardware rather than trying to use the same channel map with all hardware. "pactl list sinks" shows the actual state of the playback devices on the system. The channel map shown there is what PulseAudio actually uses. If you want to modify the surround51 channel map, you can do that by editing /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf. Search for string "surround51", you'll find the channel map definition nearby. However, that file is not meant to be modified by users - if modification is needed for the channels to be assigned correctly, that's an alsa bug, because the "surround51" device should always have channel map "front-left,front-right,rear-left,rear-right,front- center,lfe". > > > I did put this line in default.pa, which worked but without effect: > > > > > > load-module module-alsa-sink > > > sink_name=alsa_output.pci-0000_00_14.2.analog-surround-51 > > > device_id=1 channels=6 > > > channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe > > I don't know what "device_id=1" is supposed to do when given to > > module- alsa-sink.

Does the desktop stall if you revert all configuration to what it was by default? --Â Tanu
