Subject2.4.5, VIA KT133, sound corruption
Date

Hello,

I have experienced similar problems to
http://lists.kernelnotes.de/linux-kernel/Week-of-Mon-20010430/002158.html

When I send _anything_ to /dev/dsp, I get continuous high-pitched beeping
(nothing remotely resembling what the sound card should be doing).

I'm running 2.4.5 kernel with debian system, Abit KT7 (IA KT133 chipset) and
SB PC128 (es1371 driver). Similar to previous thread, removing VIA latency
patch - quirk_vialatency() in driver/pci/quirks.c works. The only problem is
that I probably have VT82C686B chipset (at least
pci_read_config_byte(vt82c686, PCI_CLASS_REVISION, &rev) returns 0x40)
but patch makes problems on my board. Motherboard is just bought so it may
be some newer version?

I have attached copy of /proc/pci. If anyone requires more information,
please sent me email. I am not subscribed to this list.

Best regards,

Mirek Ruda
