Too many mixer devices in devfs

Too many mixer devices in devfs

[Eduard Bloch]

Hello,

I noticed this behaviour in 2.4.18 and it is still reproducible with
2.4.19pre8. With devfs, the /dev/sound/ directory allways contains four
mixer devices, even when all sound drivers are unloaded. There are also
other device files that do not appear and disappear when not needed. If
this is a feature (what I doubt), then it is a very bad one. It is not
consitent with default devfs behaviour or even other versions of it.

# ls /dev/sound
audio
dspW
mixer0
mixer1
mixer2
mixer3
sequencer
sequencer2

Gruss/Regards,
Eduard.

I don't see this behaviour on my box. I get exactly the devices I
expect. I have the es1371 driver. Perhaps your driver has been broken
in a recent patch. Go find out who hacked it last and harass them :-)

Forget the whole issue. The reason is a faulty configuration script for
devfsd, installed by alsa-base Debian package. It forced the creation of
those devices, not looking for existing driver. Unfortunately, devfsd
does not remove those devices when beeing stoped.
