sound problem FC4 / disabling a module

[sedj]

Hi,

I can't seem to get any sound out of my laptop which has FC4 on it. Googling around, there appears to be a few issues with FC4 and sound.

One link I found seemed to think that the module snd_intel8x0m conflicts with snd_intel8x0 - and by disabling the former, sound works.

[Yes, the alsamixer master volume is up ]

lspci shows :

00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)

... so it appears to recognize the sound hardware.

I added snd_intel8x0m to the /etc/hotplug/blacklist file, which some site hinted would disable the module, but lsmod still shows it as being loaded :

[root@localhost ~]# lsmod |grep snd_intel8x0m
snd_intel8x0m 19589 0
snd_ac97_codec 75961 2 snd_intel8x0m,snd_intel8x0
snd_pcm 100169 4 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd 57157 10 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
snd_page_alloc 9669 3 snd_intel8x0m,snd_intel8x0,snd_pcm

Any ideas on how to disable the module permanantly ? rmmod seems to unload it temporarily, but sound still fails, so I wondered if a permanent unload would work ...

Thanks for any help.

I think you'll find that lspci doesn't prove that linux knows anything about the hardware. My understanding is that all the data displayed is read straight from the bus and the card.
Also, I'd be looking at /etc/modules.conf to see if there is an entry there for your module that your wish to disable.

Take a look and see how you get on.

I don't seem to have a /etc/modules.conf ...

Sorry, /etc/modprobe.conf

Hmmm, no mention of the snd_intel8x0m, just the desired snd-intel8x0 :

alias eth0 8139too
alias eth1 ipw2100
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias ieee1394-controller ohci1394
options ipw2100  irq=11
