Here's a strange little bug. If you tell alsaconf "yes" when asked whether you want to modify modprobe.conf, it appends this to the file:
alias snd-card-0 snd-*** debug [lib/liblow.c(205)]: alias sound-slot-0 snd-*** debug [lib/liblow.c(205)]:
instead of putting in whatever module it ought to. Both the last and current version of alsa-utils seem to be affected.
This has been an issue for a while.
From http://bbs.archlinux.org/viewtopic.php? … low#124561 found by searching "alsaconf liblow"
A google search indicated that liblow.c belongs to gpm.
If you remove gpm, alsaconf works fine. If you need gpm, then you'll need to complain to them.
man, that liblows
