Now that I've gotten your attention, perhaps you can help me with something.

For some odd reason, my sound refuses to work. I can get maybe a half-second of stuttering sound before whatever music player I'm using cuts out. This wasn't happening yesterday, after I'd gotten ALSA and udev to paly nice. But now, it wants to be a little bitch about everything.

I've checked /etc/security/console.perms and made the necessary adjustments. I've added the normal users to the audio group. I've made sure all the audio devices in /etc/udev/permissions.d/udev.permissions are set to 660.

And nothing.

Ideas, anyone?

Check to see that when you're booting the alsasound service doesn't generate any complaints about IRQ numbers. I ran into something similar when trying to use ALSA and APM. Moving back to ACPI and disabling the local APIC fixed everything for me.

After I saw that, I went into the kernel config and checked to see if ACPI was enabled. It is, and APM isn't right now.

BTW, I'm running 2.6.7-vanilla and have an nVidia nForce2 onboard sound card.
