This might be causing your problem. > # cat /proc/asound/cards > 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4 > Intel 82801DB-ICH4 with ALC202 at 0xe0100c00, irq 177 That looks OK; the card is there as device 0. I had a quick look at http://alsa.opensrc.org/index.php?page=TroubleShooting and it seems that a missing /dev/snd can indeed cause your error message (point 5 on that page). They propose to run the "snddevices" script. On Debian this is part of alsa-base and located at /usr/share/alsa-base/snddevices I have never had to use it myself, therefore I cannot say anything about it. It might be worth a try. I noticed one other thing in your lsmod output: You have both the snd_intel8x0 and the snd_intel8x0m module loaded. The latter one is a modem driver, and I seem to remember that it can sometimes interfere with the sound system. You could try to blacklist it by editing the file /etc/modprobe.d/alsa-base-blacklist. There should already be a commented-out entry for this module: # blacklist snd-intel8x0m Change this line to blacklist snd-intel8x0m and reboot. Maybe that will help. (This should prevent the snd-intel8x0m from being loaded at boot.) -- Regards, Florian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
