I've changed my motherboard to a Via Apollo VPX with a P200MMX, and my
sound card (Sound Blaster PCI128, es1371) gets noisy, sounds crackling and
popping sometimes. I've tried mpg123, xmms and freeamp. I've searched the
mailing lists, newsgroups, read the documentations of the kernel and the
modules, tried to switch off PCI Quirks in kernel2.2.14, switched off the
PCI Optimizations, tried kernel2.2.15pre3, and 2.3.99pre3, and tried to use
powertweak, too. And changed the BIOS settings. Sometimes - as I think -
there's a little change, but the crackling doesn't stop. I've also tried
ALSA and the commercial OSS. I've tried nearly everything :)

I've installed a win98 to try the card's own driver, it works, no
crackling, no popping, no noise. And I also put this card to an other box
with no VIA chipset, it worked, too.

Well... I know - or I think :) - that this VIA chipset has got some
problems and not so compatible, but what should I do? I've read in
creative's newsgroup that other ones have this problem too, and I wouldn't
try to solve this problem if this card didn't work with win98. If it didn't
work I would know that this motherboard doesn't like this sound card and
nothing to do. But it works and I would like to have it worked under linux
too :) Or should I change my motherboard?:)

Do you have an idea what to do? I can code in C and already have done some
hardware programming (but no DMA programming and I don't know how the linux
kernel works), so if someone would like me to try some code and recompile
the kernel, or what else, please feel free to drop me an e-mail. Until I
change my motherboard... :) Other ones have the same problem with this
chipset  & card so I would like to help in solving it, and to make linux a
bit better :)

Thanx for reading this, bye,
