Haiku makes scraping or chopping noises.

[Dilbert2]

Hello. I have installed the latest Nightly of Haiku on my Asus G73sw laptop. When it boots onto the desktop, I hear some noise for a few seconds. It sounds a bit like static radio noise, but not quite the same... Then it goes quiet.

I downloaded an MP3 and tried to play it in MediaPlayer. As soon as I hit Play, the noise starts louder and more annoying than before.

The noise is similar to what I remember from the old days, Playing Commander Keen on Windows 98, when suddenly it crashes. The same millisecond of the audio track plays in a loop, like a piston engine or machine gun.

If I hit Stop or Play, or quit MediaPlayer, the pitch or volume of the noise can change. But it's still there.

Haiku's volume control does NOT affect the volume of this noise.

Everything else seems fine. The computer does not hang, it's just playing terrible noise instead of music.

I would try alpha 3, but it fails to boot altogether. So I don't know if it's an old bug. It is a wery new gaming laptop with Sandy Bridge. Here is the output from lspci in Ubuntu:

Tell me if you need more info to solve this.

The problem happens both when running live off a USB stick, and when installed on hard drive.
