ok I am fairly new user of linux. been using solaris for years but new to linux.

I am running redhat 9 on a AMD 2500+. I have an asus a7v8x-x motherboard with the build in sound card. running sndconfig recognises my sound car but I am having IRQ conflicts. I loaded the alsa drivers with no problems but it still won't play sounds.

my question is how do I change in redhat what IRQ the sounds card wants? I have tried in the bios but can't get it to change the irq assigned to it.

here is the relivent information:

[root@linux root]# dmesg |grep irq

ANY help is appriciated.

thanks!

"my question is how do I change in redhat what IRQ the sounds card wants?"

I think that you make your changes in /etc/modules.conf. What those changes are in your case, I have no idea. Scan down the /etc/modules.conf until you hit a lot of commented out lines having to do with sound card configuration and see what you can make of it.

here is my /etc/modules.conf

I don't see anything in there to change:
alias eth0 via-rhine
alias usb-controller ehci-hcd
alias usb-controller1 usb-uhci
alias char-major-195 nvidia
#alias sound-slot-0 via82cxxx_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1
|| :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 |
| :
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-via82xx
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

In 2000, and again in 2001, I had to configure my IRQ and so forth to get a SoundBlaster card working on SuSE 6.4 and 7.2. Here are the lines I added to /etc/modules.conf in 2001 to get it working on SuSE 7.2:

alias char-major-14 sb
post-install sb /sbin/modprobe "-k" "adlib_card"
options sb io=0x220 irq=5 dma=1 dma16=5 mpu_io=0x330
options adlib_card io=0x388

The only relevance that I can see this code having to your problem is that it shows that you can reconfigure your IRQ and so forth in /etc/modules.conf I remember that I worked on the problem off and on for several days but I don't remember enough about what I did to apply it to your problem. I think that I got part of the necessary information from the comments in /etc/modules.conf, part from SuSE support, and part from SoundBlaster support.
