FC4 sudden sound card problem

[Brad Kligerman]

Hi all::
I had a FC4 installation & CCRMA working fine. I then got a wifi card running, and for some reason it knocked out my sound card. But, when I reboot with the original FC4 kernel, the soundcard shows up again.

for CCRMA =>
/proc/asound/cards
0 [U0x46d0x8b0    ]: USB-Audio - USB Device 0x46d:0x8b0
                    USB Device 0x46d:0x8b0 at usb-0000:00:1d.0-1, full speed
1 [Modem          ]: ICH-MODEM - Intel 82801CA-ICH3 Modem
                    Intel 82801CA-ICH3 Modem at 0x2400, irq 9

for FC4 =>
cat /proc/asound/cards
0 [I82801CAICH3   ]: ICH - Intel 82801CA-ICH3
                    Intel 82801CA-ICH3 with YMF753 at 0x1c00, irq 9
1 [Modem          ]: ICH-MODEM - Intel 82801CA-ICH3 Modem
                    Intel 82801CA-ICH3 Modem at 0x2400, irq 9
2 [U0x46d0x8b0    ]: USB-Audio - USB Device 0x46d:0x8b0
                    USB Device 0x46d:0x8b0 at usb-0000:00:1d.0-1, full speed

modprobe.conf (kind of a mess...)
alias eth0 e100
alias eth1 prism54
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0 options snd-intel8x0 index=0 install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && \
       /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; \
       /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller uhci-hcd
alias ieee1394-controller ohci1394
alias net-pf-10 off
alias ipv6 of

Any ideas??
Thanks ::Brad

Which Planet CCRMA kernel is this? As you say, weird. You should take a
look at /var/log/messages and/or the output of dmesg to see if there are
error messages related to the audio drivers. What happens if you try to
load the soundcard kernel module by hand? (ie: "/sbin/modprobe
snd-intel8x0")

One possible scenario is that the wifi driver is using some hardware
resource that the soundcard needs as well...

The "sound comes back when booting into fc4's kernel" is to be expected
as you only installed the driver for CCRMA's kernel (and that's what is
apparently causing the conflict).

 From /var/log/messages ==>
Jul  7 18:09:53 localhost kernel: Loaded prism54 driver, version 1.2
Jul  7 18:09:53 localhost kernel: snd_intel8x0: Unknown parameter
...
Jul  7 21:34:00 localhost kernel: usbcore: deregistering driver
snd-usb-audio

 From dmesg ==>
e100: eth0: e100_probe: addr 0xe8200000, irq 9, MAC addr 08:00:46:68:86:3C
Loaded prism54 driver, version 1.2
snd_intel8x0: Unknown parameter `'
snd_intel8x0: Unknown parameter `'
snd_intel8x0: Unknown parameter `'

if you look at my /proc/asound/cards (below) you'll see that the sound
card uses irq 9 also.

I didn't seem to have this problem in RH9, FC3 & CCRMA, the same wifi &
sound cards.

Well, no, in fact, the wifi card is functioning with both the FC4 &
CCRMA kernels.
Can I change the irq being accessed by the sound card or the network
card? I thought these problems disappeared with DOS?

Well, then there are problems with the parameters that are being passed.

"options snd-card-0" is repeated twice in the same line...
