invalid mixer device

Smokey · 09-21-2004, 06:49 AM

unable to open audio device "/dev/mixer"
Please Check that you have permissions to open "/dev/mixer"
and that you have sound support in your kernel

when I run "alsaconf" as root it says this:

No Supported PnP or PCI card found
Would you like to probe legacy ISA Sound Card/Chips

Then it says No Legacy drivers are available

smokey@darkstar:~% alsamixer

alsamixer: function snd_ctl_open failed for default: No such device

I reinstalled Slackware 9.1 earlier and before hand, I was running -current and sound was working just fine, but now I reinstalled 9.1 and kept all the existing packages intact and if there were any updates for 9.1 I downloaded and used upgradepkg but sound doesnt work still?

Reinstalling alsa-driver and alsa-lib might do the trick. For some reason after every kernel recompile I need to do this. Hope it helps.

Reinstalling the packages, or reconfiguring alsa from source?

i removed the packages and installed them again but still nothing.

Hi,

Whether you install alsa packages or compile it from source the result is that alsa kernel modules will be placed in the directory /lib/modules/2.x.x/kernel/...
If you've reinstalled Slackware 9.1 then you're using a different kernel/kernel modules and so you need to reinstall or recompile the alsa modules so that they are placed in the proper modules directory.

Whenever I have any problems with alsa, reinstalling the packages does it for me. But as I read above, it didn't work out. Maybe someone else has a brighter idea?

Could it have anything to do with the recent upgrade of alsa-driver for the 2.4.27 kernel? Check which alsa-driver package you have and see if it matches your kernel.
