Another sound problem! No /dev/dsp*

I'm always having sound problems...

I have no sound in 2.6.10, but I do in 2.4.26. Here's the output of lsmod (same modules are loaded in both kernels):

Code:

When I started MPlayer, it told me that /dev/dsp could not be found, so I checked, and it's not there. When I load up 2.4.26 it is, though. Running the snddevices script that comes with alsa-driver doesn't seem to fix the problem. Anyone have any ideas?

have you run alsaconf, alsamixer and alsactl store?

And you are using udev?

voyciz · 03-03-2005, 03:12 PM

Yes to all the above.

Ach, you know what? I don't think I enabled devfs when I compiled the kernel...do I need this?

EDIT: Nevermind, answered my own question. Read with menuconfig that udev replaces devfs.

OK, new situation. I figured that the only thing that was different between 2.4.26 and 2.6.10 was that 2.6.10 has alsa builtin. So, I recompiled without it and built alsa-driver-1.0.8, alsa-lib-1.0.8, alsa-oss-1.0.8, and alsa-utils-1.0.8 and installed them all. I configured the card with alsaconf and things went fine, but now some of the channels are seemingly non-existant; they show up, but they are stuck at 00, can't raise them. When I use "alsactl restore", I get:

Code:

alsactl: set_control:930: warning: name mismatch (Master Playback Volume/Center Playback Switch) for control #2
alsactl: set_control:1046: bad control.2.value.0 content
