Crackling sound in some applications.

[Sebastian]

When i run some applications - mostly games i get a annoying crackling sound. My guess is that it's a bad driver.
I have a AD1981 sound chipset on a nx9420 laptop.
I get this error message when i run a certain game using aoss to emulate OSS:
FSOUND_Output_OSS_Wait : Timeout on audio write. Caused by bad driver!

I have a crackling sound with Rhythmbox but not all the time.
My sound chipset is HDA ULI M5461.

I have the same.

this started in feisty. Stuck around on gutsy, and still present in hardy on my asus laptop with ac97 chipset. Anybody have a solution?

Appeared on my ATI SB450 HDA after upgrade to Hardy

The effect is significantly different depending on bitrate, a 128bit stream / MP3 is unbearable while at 320k it is hardly noticeable.
