Package: alsa-base
Version: 1.0.21+dfsg-2.1
Severity: important
When my USB MIDI Controller (M-Audio Keystudio 49) is not plugged in on
startup, alsa recognizes my sound card, and sound works fine.
However, when I plug in my controller before starting up, alsa does not load my
sound card.
Note that everything works fine (including the controller) if I plug in the
controller after booting up.
It seems to me that the problem is that alsa thinks that the MIDI Controller is
my sound card, and thus does not load the actual one.
