Thread: Sound: auto 2.0 5.1 7.1 configuration possible?

-

dear all,

have amplifyer 5.1 speaker system, analog , digital in/out may needed.
connect linux multimedia pc/laptop or whatever.

use to:
- listen cds (stereo)
- watch movies (5.1 or 7.1 audio channels)


there way setup audio environment when play 5.1 audio channels correctly routed speakers without mixing , when play stereo audio 5.1 speakers active?
have looked in various threads people explain how config alsa, have not found yet solution works 2 situations @ same time.
or wrong?


thanks,
leodp

if use alsa without pulseaudio, .asoundrc should trick:
code:
pcm.!default {      type plug      slave.pcm {          type asym          playback.pcm {              type dmix              ipc_key 10001              slave {                  pcm "hw:0"                  channels 8              }          }          capture.pcm "hw:0"      }      route_policy duplicate  }
"route_policy duplicate" makes alsa copy channels if number of client channels lower number of slave channels set 8. 5.1 soundcard change "channels 8" "channels 6".
