Summary: Capture happens only on one channel
Description:
When I am playing a CD, if I capture the sound output via the capture
channel OR the CD channel (amixer output attached), the captured sound is
only one one channel (the right one) and is very distorted.
The audio plays normally in stereo on the speakers.

I have the same symptoms on my system:
Capturing Line, works only on channel 1, channel 2 is silent,
although with some noise.
I figured out that switching the Mic Boost on changes (boosts)
the noisefloor of the silent channel 2.
Some tests with a Microphone confirmed that channel 2 records always
the Mic input, independently of any capture source settings in mixer.
Switching Capture off in mixer does work (silence on both channels
without noise). However, switching capture source is only effective
on channel 1. Channel 2 keeps listening to Mic input.

Alsa.conf is part of the libasound/alsalib librairie. Did you tried to
install another version of this librairie? I think the problem come from
this librairie.
