[Bug 382140] Re: karmic: high-pitched noise from snd-hda-intel

[Andrey Skvortsov]

I have the same problem with this noise. I thought also that it is not
driver problem and the reason is electronic interference on the
motherboard. But I noticed, that iif CPUs work at 100%, there are no
noises!!! Can somebody explain me this wonder?

I tested this with simple program:  "int main(void){ for(;;); return 0;}"
If each core execute a program, there are no noises!

Notebook Dell Vostro 1500. Ubuntu 9.10  Kernel 2.6.31-21, ALSA 1.0.20.
