another sound issue, this afternoon when i logged into gentoo, i noticed the speaker icon had the " x" across it and when i moved my mouse over it, it read muted. so I double clicked on it, and unmuted whatever was muted and proceeded to listen to my mp3's, well to my surprise amarok was playing the mp3 but without sound. i tried gxine with the same results. Now i, dont remember doing anything drastically except running emerge --sync and maybe installing other programs from portage. im not getting any errors, i check to see if all the connections and everything seems fine. now i have two sound cards, the onboard nvdia soundcard and pci soundblaster soundcard which if i remember correctly is the one i set up also to use. anyway, here is some info, hope someone can tell me whats going on, thanks

ok i fixed the problem temporarily. yesterday i ran alsaconf and set up my pci card and was able to get sound. tonight i got back from work logged in, and try listening to some mp3, and no sound again. i checked my sound setting and it had reverted to using the onboard nvidia soundcard again which is not the one i configured yesterday. is there something that could be taking place during reboot that resets the soundcard back to the onboard card???

here is my /etc/modules.d/alsa

Alsa 0.9.X kernel modules' configuration file.
# $Header: /var/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.conf-rc,v 1.5 2006/06/13 10:18:25 uberlord Exp $

# ALSA portion
# OSS/Free portion

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `modules-update' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.

alias /dev/mixer snd-mixer-oss

alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.

any help is appreicated.

First stop alsasound.

Then use this as your /etc/modules.d/alsa:

If you don't use your onboard soundcard you could do what I do and just disable it in the bios
Bit of hack but also free's up IRQ's etc

im still having sound issues. i will try disabling the onboard sound from the bios and see if that works. for now i have to run as root /etc/init.d/alsasound stop and then start to be able to get sound. kinda of sucks. i will also some of the solutions suggested in this thread. thanks for the tips.
