In my experience this helped avoid sound corruption when joining the track,
but the problem could still come back after a shift-R etc.
One other, fairly drastic option that I successfully tried was to disable
ACPI in Win2k. Disabling it in the bios makes no difference to IRQ
assignments in Windows, which I think is where the problem lies. Your
graphics card and soundcard are probably sharing the same IRQ under ACPI,
and disabling it will allow them to take the IRQs specified by the bios
instead if Windows.
To do this you need to open the device manager and change the driver called
'Advanced Configuration and Power Interface (ACPI) PC' to 'Standard PC'.
This is not a simple thing to do, and may require a format & reinstall if it
goes wrong, so take a backup etc if you try this, and don't try it at all if
you're not absolutely sure about what you're doing.
This should cure the sound distortion but you will lose pretty much all
power management, eg. your PC will no longer automatically switch off when
you shut down Windows.
Please note that I do not recommend trying this if you are not sure how to
recover your PC if it fails to boot (ie if you get it wrong), and you do so
at your own risk.
It worked for me, plus cured a few other conflicts I was having at the time,
but I changed it back to ACPI when I found out about lowering the hardware
acceleration, since that cured it for me.
