(Sorry for the direct CCing - didn't know if this was relevant or not and I've been asking around for weeks - just 'D' it away if it annoys you)

My AWE is acting up on a vanilla 2.2.14 build. I'm configuring it via isapnp and using modules loaded via kmod & modules.conf. It's detected as an SB 4.16 - and it plays fine for normal playback (average midi and dsp usage).

I am not loading the awe_wave module, and I don't think it matters much.

If I change volume on this card _while it's playing_, however, I get broken sound, DMA timeouts and general crap out of the speakers. This only happens if I touch the mixer - if I don't, it's all fine. I can twiddle with the volume a bit to get the sound to come out unbroken again.

What problem could this be a symptom of?

It's a CT4380 - anybody have a similar card?

Forget the rest if this is an obviously known problem.

I can downgrade the kernel to test if it seems like the proper thing to do
- has anyone been testing this card lately?

On an unrelated note - is it proper that I (ACT Y) the card during isapnp?

To use the wavetable you need to load this module - see the two extra lines for isapnp.conf below
