I have a strange problem with alsa. For some reason, I have sound ONLY if I do the following:
1. Start the PC (obvious haha :P) 2. Log in as root 3. Log out (I do nothing as root) 4. Log in as user
Then, as 'user' the sound works fine. BUT when I don't log as root first, but log as 'user', I get the message "Can't open the /dev/dsp device (no such device). Redirecting output to /dev/null".
The sound works fine as root, too. I think there should be some problem with permissions or so (??) I don't know... or maybe it could be a module problem, because of the output of '/var/log/messages'... Does somebody of you have an idea?
I have an integrated audio system, the AC'97 Audio Codec, in the ASUS P4PE motherboard. Here I have attached some outputs of my system, such dmesg, lspci, and so. Please tell me if you need more information.
Thank you in advance.
Regards,
R.C.
