Sound garbled; ERR: 1 on interrupts

[pairajacks]

I've been fighting what I think is an interrupt issue. My mobo is ASUS A8N-VM CSM, and I'm on Fedora 5. The sound is an onboard SoundMax AD198x which is using an ALSA driver (1.0.13)

Boot hangs a little at "Udev: " , then it reports something like "Disabling IRQ 209". Alsamixer sometimes works, sometimes doesn't, but sound is always garbled.

Control Center/Sound & Multimedia/Sound System reports:
Error - Unable to start the sound server to retrieve possible sound I/o methods
Only automatic detection will be available (Note that sound works fine on KnoppMyth R5D1)

My interrupts look like this: Note the ERR: 1 (It's always libata that has the 100000)

what does dmesg say? any conflicts during boot?

[pairajacks]

This time I saw "Disabling IRQ # 217" and "2041 Segmentation fault" This is a new error.

[stoggy]

in your bios what are resources controlled by os or bios?


check your kernel and make sure pnp is enabled.

[pairajacks]

Sorry for taking so long to get back; I'm swapping between MythDora and KnoppMyth Installations (two harddrvives). MythDora is showing *lots* of problems; Knoppmyth working fine. Other people with same mobo (A8n-VM CSM) report OK with MythDora 3.2. (note all the outputs I'm showing here are the MythDora intallation)

Anyways in bios; PnP is enabled, all IRQ's are enabled for PCI (other choice was to reserve for an IRQ for ISA). Not sure if this means anything, but disabling Legacy USB support in the bios (was recommended for this mobo) but system hangs ...I think that's what it did; at any rate, it choked during boot. Still having sound issues; garbled sound, and an ERR=1 as mentioned before on interupts.

[stoggy]

is pnp enabled in the mythdora kernel?

[pairajacks]

Hmm, I didn't realize the kernel could be disabled for pnp. I found some obscure references to kernel pnp enabling, and that it's mostly for ISA cards (my ASUS A8n-VM CSM doesn't have any ISA slots).

How can you tell if the kernel has pnp enabled? (MythDora uses a Fedora 5 core)

[stoggy]

If you rebuilt your kernel it will be here. If your using a stock kernel pnp is enable.
grep -i pnp /usr/src/linux/.config #you might have renamed the file

in fc6 this file is saved in boot as: Might want to check there
/boot/config`uname -r`

what is the output from: This will tell us how the kernel was booted maybe nopnp is set there?
cat /proc/cmdline


Must have been really tired when i first read this post i went back through your original post and pnp is enabled in the kernel... check the
cat /proc/cmdline

though maybe something else is causing problems there. your acpi isnt being recognized you might want to try disabling and seeing if you can boot up any better. When you get to grub screen hit "e" and then arrow to the kernel= line and hit "e" again. add noacpi to the line and then hit "b" to boot the kernel with acpi disabled.

when booting and at the grub menu
highlight the myth you want to boot and hit "e" then highlight the kernel line and hit "e" again. Then add noacpi to the line and then hit "b" ... this isnt the best way to run but maybe you can see better what is happening with acpi turned off and it isnt being detected when you boot. Maybe the wrong acpi module is loading?. once up try:
modprobe asus_acpi

watch for errors

kernel line will look something like this...
kernel /vmlinuz-fc6 ro root=/dev/1/LV1-01 rhgb quiet noacpi
