No sound in some apps and games (sdl permisson problem)

Hi!

Some weeks ago, witout rebooting, the sound in some games and apps stop working. The problem is that not in every app. For example, y could hear music in flash, openttd, or audacity. But in other software, there is not sound at all. I think the problem is sdl-related (if it whas something of /dev i assume i sould not hear any sound at all).

The second problem is that i can't see any error anywhere. For example, when i run quake:

S_Startup: initializing sound output format: 48000Hz, 16 bit, 2 channels...
SndSys_Init: using the SDL module
Wanted audio Specification:
        Channels  : 2
        Format    : 0x8010
        Frequency : 48000
        Samples   : 2048
Obtained audio specification:
        Channels  : 2
        Format    : 0x8010
        Frequency : 48000
        Samples   : 1024
Sound format: 48000Hz, 2 channels, 16 bits per sample
Found 1 cdrom drives.
No CD in drive 0.
CDAudio_Init: No CD in player.
Can't get initial CD volume
CD Audio Initialized
========Initialized=========


This means it finds and uses the sound card correctly, but it is muted anyway.

The sound problem seems to dissapear if i run the games or apps affected as root, but i don't like the idea of executing software as root witouth need.

Any workfixes? Thanks in advance
