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.

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

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

Please excuse me if I'm being naive, but aren't SBlive cards really bad bus
citizens and have problems on SMP machines, Via chipsets, etc.?

Or did Linux fix what Creative and Microsoft couldn't.  Or won't.  ;)
