Hello

I've recently encountered this error message when playing a video with
mplayer (it repeats endless times):

> ALSA lib control.c:654:(snd_ctl_open_noupdate) Invalid CTL /dev/mixer0%
> alsa-control: mixer attach /dev/mixer error:
> Datei oder Verzeichnis nicht gefunden

mplayer has worked without any problems before. I did some changes to the
system, to make my sound blaster card be the system wide default choice
(/usr/share/alsa/alsa.conf defaults.pcm, defaults.ctl etc), but undoing them
didn't resolve the problem.

This is a strace about what dev files were accessed:

> [root | programme]# strace -f gmplayer 2>&1 | grep /dev
> open("/dev/snd/controlC0", O_RDONLY)    = 14
> open("/dev/snd/controlC1", O_RDONLY)    = 14
> open("/dev/snd/controlC1", O_RDWR)      = 14
> open("/dev/snd/pcmC1D0p", O_RDWR)       = 15
> write(2, "Invalid CTL /dev/mixer", 22Invalid CTL /dev/mixer)  = 22
> write(2, "alsa-control: mixer attach /dev/"..., 83alsa-control: mixer
attach /dev/mixer error: Datei oder Verzeichnis nicht gefunden

Im using mplayer-1.0-35_pre5.rhfc2.at

Any help is appreciated. Btw, XMMS works fine using the alsa plugin.
