...

do you mean that it only work on HDaudio and not intel8x0 ?

How about other drivers ?

It's driver/hardware specific, I guess everyone would have to enable this in their drivers. I don't understand what 8x0 does...You're welcome to test and do the same for 8x0 if you have the specs and know how to disable interrupts.

Any side effect of this disabling interrupt ?

Do you mean that all applications must use pulse api instead of alsa-pulse plugin ?

Did your test included those voip application which require low latency ?

did your test only play one audio stream to the sound server ?

Do those alsa application still work with "hw" device when pulseaudio is disabled ?
