While still trying to figure out whether or not it's possible for me
to record from my Line,0 with Playback [off], I came across your reply
to someone who was trying to get capture to work from a script
(similar to what I'm trying to do).
Your suggestion does seem to turn capture on/off temporarily, but the
next "amixer get Line,0" shows "Capture [off]" whenever Playback is
also off.
$ amixer sset Line,0 capture nocap | grep " Front"
Front Left: 24 [77%] Playback [off] Capture [off]
Front Right: 24 [77%] Playback [off] Capture [off]
$ amixer sset Line,0 capture cap | grep " Front"
Front Left: 24 [77%] Playback [off] Capture [on]
Front Right: 24 [77%] Playback [off] Capture [on]
$ amixer sget Line,0
Simple mixer control 'Line',0
Capabilities: volume pswitch cswitch
Playback channels: Front Left - Front Right
Capture channels: Front Left - Front Right
Limits: 0 - 31
Front Left: 24 [77%] Playback [off] Capture [off]
Front Right: 24 [77%] Playback [off] Capture [off]
Is this expected? I can get another sound card just for capture if I
need to, but I'd rather not if my current card (AudioPCI) is capable
of doing the job quietly.
Thanks much.
