2.4.4 has broken sound here in a very strange way. I have a debian testing
system, Abit KT7 (thus VIA KT133 chipset) and SB PC128 (es1371-based) sound
card.

Up until 2.4.3 everything was fine. Now, however, when I send _anything_ to
/dev/dsp, I get continuous high-pitched beeping (nothing remotely resembling
what the sound card should be doing).

The strange thing is that when I cause hard disk activity (find / -name "*")
the correct sound is produced in time with hard disc accesses (I have tried
this with DMA enabled and disabled on the drive, same results). Also, when I
switch desktops (icewm, XFree86 4.0.2, Nvidia 0.9.767 drivers) the correct
sound is (very) momentarily produced (almost non-detectibly). After these
periods of lucidity, the sound card returns to its high-pitched cacophony.

I have attached copies of both /proc/interrupts and /proc/pci. If anyone
requires more information, please say the word. I am not subscribed to this
list.

Best regards,
