No, I hadn't used the ALSA modules :) The
interrupts get through unless
I use < 2048 samples / period, if I do ALSA reports lost interrupts
constantly.
hrrmm...I doubt if it is due to IRQ priorities. I mean, really, any modern
CPU can handles 10s or 100s of thousands of IRQs per second..
This does not
show a particularly high interrupt load, either. It does show
that you get about 70 video interrupts per second (ask nvidia!) and it shows
that you seem to have the timer at 1024 HZ (lowlatency patch?).
You get one per screen refresh dont you?
