I've been using alsamixer, as well as other mixers (both alsa and
oss), but I've found no combination of settings that works for
the LINE-INs. The controls I see are:

# amixer scontrols ###################################################
Simple mixer control 'PCM',0
Simple mixer control 'PCM Capture Source',0
Simple mixer control 'PCM',1
Simple mixer control 'Mic',0
Simple mixer control 'Auto Gain Control',0
Simple mixer control 'Speaker',0
Simple mixer control 'Speaker',1
######################################################################

I've tried every reasonable combination, but I still capture
nothing from those inputs. I've tried 'PCM Capture Source' in
each of the three settings ('Mic', 'Input 1' and 'Input 2'). I've
enabled capture for PCM and PCM 1. I've tried every combination
of CAPTUR settings and I've unmuted everything.

If someone would be kind enough to post an 'asound.state' file
that is known to enable LINE-IN input, I could at least rule out
that as being the problem.

thanks,
steve
