Hi,
[1] With kernel-2.4.19 and kernel-2.4.20 the sound stutter, sizzle

[2] The problem seems be correlated with my PCI graphic card (matrox G200 PCI) and my sound card (sound blaster live 5.1).
In fact every time I listen music and that something appens on my screen (moving a window, watching a movie) the sound stutter.

Make sure you have the XFree86 settings for the Matrox right -in paticular the PCI retry option

I was thinking about a problem with my chipset (AMD760MPX, motherboard tyan tiger MPX); because I have done some tests on a PC with a matrox G200 PCI and a sound blaster live, with a chipset via KT333 and the problem doesn't seems to occur. Is it possible?

Could be - the newer kernel supports IDE DMA, and in my experience the AMD76x has serious fairness problems (I gave up using it for video capture)

This doesn't reassure me :-) but I didn't get the choice for an SMP machine with some athlon processors.

Note that I am also able to use IDE DMA with the kernel 2.4.8 (ie hdparm -d 1 /dev/hd. works)

So now, do you want me to try other kernel version in order to find in what version the problem appeared?

I think the first thing I should do is to try different kernel version in order to find when this problem appeared first.

I had a similar problem. Turned out to be where my TV card was plugged into + my mixer settings. I had the tv sound out plugged into mic, instead of line in. Using aumix I was able to figure out that changing which input was allowed to recored got rid of the noise. Have you attempted such trouble shooting?

Thanks for the reply,

I don't think this is the problem, because nothing is plugged into mic or line in; and all settings are set to 0 in aumix except Vol, Pcm and OGain.

But before I spend time to do this, I would like to know if someone is going to help me to find the problem.

If I get a positive response, I will do my best to help to find the bug. But If you think this problem isn't really important, I don't want to spend hours to find the problem ...

[3] Keywords:
~ modules: OSS or ALSA (same problem with both)
~ kernel: 2.4.20 (official), 2.4.19 at least. But it works fine with 2.4.8

[8] Some informations that may be usefull
*** Just down-grading to the kernel 2.4.8 solves the problem *** I have several graphic cards in my P.C. (one AGP and 2 PCI), but using only one PCI cause the problem to occur.
*** I have a SMP machine, but I have tried using only one processor, same problem.
*** I have tried official kernel 2.4.20, with the same problem *** I also tried to use OSS emu10k1-v0.20a drivers: always the same:
problem doesn't occurs with 2.4.8 but occurs with 2.4.19 and 2.4.20 *** I was thinking about some timings changed for PCI bus since kernel 2.4.8 ?

*** As I said before, if I get a positive response, I will do my best to help to find the bug. But If you think this problem isn't really important, I don't want to spend hours to find it ...

Thanks,
Xavier
