Description of problem:
Bug in ALSA drivers that I don't understand enough to describe in detail. I am a user and not a Linux programmer.

Observations:
- Trying the "test call" feature in Ekiga shows that although mike input is recognised, it doesn't get forwarded to Ekiga. PulseAudio still has it, Ekiga does not.
- Mike recording itself without ALSA (e. g. to harddrive) works.
- ALSA errors written to log file every three seconds or so.

A senior RedHat programmer then told me I should file this as an ALSA bug after seeing the screenshot.
  
This may be related to PulseAudio, but after a while everything pointed towards a bug in ALSA. And given that ALSA is part of kernel and there is no category "ALSA" I was recommended to file this as a kernel bug. This may also be related to a bug in the driver(s) for my soundcard (it's a laptop), but again, a senior RedHat programmer then recommended to file this as an ALSA bug.

Actual results:
See screenshot and lsmod | grep snd output

Expected results:
ALSA drivers are supposed to work.

Additional info:
