Alsa-lib 1.0.10 had a bug that prevented capturing stereo input from line-in with many types of sound cards (those using the "simple mixer" API, such as AC97 cards).
Several responders to support request ticket #1000 indicate that they experience this problem: https://launchpad.net/distros/ubuntu/+ticket/1000
The alsa developers fixed this bug in alsa-lib 1.0.11. Here is the (very small) changeset from the alsa CVS: http://hg-mirror.alsa-project.org/alsa-lib?cmd=changeset;node=71eb744cd5be42cd7ebd14edf5f3f2e2da6ba35d;style=gitweb
I have taken Dapper's alsa-lib 2ubuntu4 and added a dpatch that incorporates this small fix. Here is a debdiff: http://boxybutgood.com/jeff/alsa-lib_1.0.10-2ubuntu5.debdiff
It would be great if you can release this as an update. It's a pretty serious bug to anyone interested in audio capture. Thanks!
