[Alsa-user] amixer failure: "Invalid CTL default"

[George <l0i...@sn...>]

Hi,

I just bought a Delta 44 to use with ALSA and I'm having trouble getting
it working.

I tried the stable release first but it didn't work with EsounD so I'm
using 0.9.0beta12.

Everything works up to the point where I execute amixer.  I get the
following message:

    ALSA lib control.c:601:(snd_ctl_open_noupdate) Invalid CTL default
    amixer: Mixer attach default error: No such file or directory

I'm using the 2.4.18 kernel and devfs.  After scanning through the bug
database I noticed problems with kernels 2.4.14+ so I tried 2.4.14 but
there was no change in the problem.

Below I've included everything relevant I can think of.  I've never used
ALSA before and I'm really excited about getting this working.  Please
help.

Thanks,
George
