That's a good question.

If PA has drop outs and logs about them when run with -vvvv is passed
then it is very likely one of the broken drivers (or your kernel
sucks). Check the pa logs for anything suspicous.

Intel HDA is a spec, not so much a chip. To figure out the actual chip
look at /proc/asound/pcm.
