Using google I found: http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg09647.html saying: "so i looked up the pci register fix put the line "install snd-au8830 /sbin/setpci -d '12eb:*' 40.B=ff ; insmod snd-au8830" in my modules.conf and everything worked fine." I'm not sure if this really works, because I had no /etc/modules.conf . Now I do (-;
** Description changed: This bug already existed in Dapper, Edgy and now in the Feisty alpha, too. The sound card is a Aureal Vortex and the used driver (I think it's the driver - could be model name, bur I don't think so) is au8820. BUG: A programm using sound is running, after it's closed no other app will be able to send sound to the driver. DMESG tells this: I think this is the bug, because this appears each time it bugs...
