[Alsa-user] "Invalid CTL default" with ALSA apps

[Oliver A. <ol...@th...>]

Hi, all.

I've been unable to use the alsa-utils applications since 0.9.0beta5
(0.9.0beta4 worked without problems).
The driver, library and utils all compile fine, but attempting to run them
produces, eg.:
----
[oliver]$ alsamixer
ALSA lib control.c:534:(snd_ctl_open_noupdate) Invalid CTL default

alsamixer: function snd_ctl_open failed for default: No such file or directory
[oliver]$
----
or (running as root, in case that's the problem):
----
~# alsamixer -c 0
ALSA lib control.c:534:(snd_ctl_open_noupdate) Invalid CTL hw:0

alsamixer: function snd_ctl_open failed for hw:0: No such file or directory
~#
----

There don't seem to be any messages about this, so I'm pretty sure it's my
configuration, but I don't really know where to look. OSS emulation works
exactly as it should, but none of the ALSA-native stuff will.

Could this be a file left lying around from an older installation of ALSA?

snddevices has been run since alsa-driver was rebuilt, and modules
snd-card-sb16, snd-pcm-oss, snd-mixer-oss and snd-seq-oss are modprobed.
/proc/asound/sndstat gives:
----
Sound Driver:3.8.1a-980706 (ALSA v0.9.0beta7 emulation code)

Thanks for any help anyone can offer.

PS. Please CC: me as well as the list, if possible; I'm not subscribed,
but I'll try to regularly check the archive.
