Description
My hardware has recently changed twice and problems still exist.
VIA8235 (snd-via82xx) → VIA8237 (actually C-Media CMI9761A; snd-via82xx too) → Creative Sound Blaster Audigy SE (snd-ca0106)
You can't tell me it's hardware question, because the hardware is first quality.
Also, NVIDIA's driver and Ralink's WiFi? firmware aren't the problem. PA < 0.9.10 had no problems with crackling and skipping at all. Some rewrites might have happened in between.
All the time I'm having the >= 0.9.10, PA is spamming (almost every second!) in /var/log/messages with:
[[[ ALSA woke us up to write new data to the device, but there was actually nothing to write! ]]]
tsched=0 makes PA crackle even more.

openSUSE 11.1, PA 0.9.14 from a testrepo (to try out if bug appears in non-distro version; 0.9.13 is shipped).

Interesting is that when I turn on "CAPTURE feedback" playback control on, PA crackles when I'm typiing, scrolling etc.
Also, any SDL app makes PA go crazy, regardless of SDL_AUDIODRIVER. SDL_AUDIODRIVER=esd makes PA crackle less than in SDL_AUDIODRIVER=pulse mode. Funny.

If more info needed, just ask.
