| |
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 ...
