Ok, so heres the deal.
I had a power outage the other day, and ever since then things have been not quite right in my linux world. Mostly with permissions. The most noticeable issue is the audio. There is none. My first thought was that a module failed to load, so I checked, and everything appears as it should. So I ran a trace on alsamixer, because it was saying no devices found, figured out that I had a permission problem on
I also ran Mplayer on a video, and it comes back with:
Code:
audio_setup: Can't open audio device /dev/dsp: Permission denied
I checked permissions on these files, and they state:
Code:
crw-rw---- 1 root audio 14, 3 2009-03-01 00:49 dsp
crw-rw---- 1 root audio 116, 0 2009-02-28 16:49 snd/controlC0
Which looks correct to me. So I looked to ensure that I am in the audio group. Here is where it gets wierd. My user was not in any of the groups it had been in before (disk, audio, cdrom, etc, etc). So I added it back into the groups, and checked /etc/group to confirm that the changes had been made, and they HADN'T.
Does anyone know how often the group file is updated? Is it updated immediately after modification of group info?
I tried backing up my group file and modifying it manually, and that hasnt fixed the problem.
Also, another wierd thing to note is that in my gkrellm, all of my sensors disappeared, which was setup using a modified amd sensor to work right with my quad-core, but thats a different story. But all of this happened all at once, which I believe that it is all related.
Any ideas on where I should go now?
Thanks
