aRts: "device /dev/dsp can't be opened", possible
I did some research on my soundcard problem and via lsof | grep "dsp" (LiSt Open Files) I found out that "ogg123" is keeping my sound devices open. Killing ogg123, an ogg player similar to mpg123, doesn't help (ps -A | grep "ogg123" and kill - 9 {process numbers}).
Now I get " can't start sound i/o" when running artsd or use the KDE configpanel.
sudo lspci -v output:
Code:

Apropriate dmesg output:

i810_audio: only 48Khz playback available.
i810_audio: AC'97 codec 0 Unable to map surround DAC's (or DAC's not present), total channels = 2
I'm pretty shure that my card is supported by the kernel (heck the dsp* devices exist) by the i810 module.
[edit]Something 'fishy' I found out. Doing a modprobe -r i810 doesn't remove /KNOPPIX/dev/dsp* which it should do, isn't it? Could it be that some other driver gets his hands on the card first so i810 doesn't recognise it anymore? Changing the order the order modules are loaded could help then.
Does anybody know more about this?
