Summary: playing 2-channel sound on surround device uses rear
speakers
Description:
If I play regular 2-channel stereo sound specifying device "surround51" or
"surround40" (or either of those with a "plug:" prefix) the sound is
output on the rear speakers. 6-channel playback is correct.

Maybe I was unclear. The sound appears *only* on the rear speakers. The
front speakers remain silent. Surely this is not what users want?

OK then it's a problem. But you mentioned that 6-channel playback work, so
basically all channels work unless you pass 2-channel samples?
Anyway, try to update alsa-lib to the latest version. There were bugs in
alsa-lib regarding channel routing.
