This bug was caused because we implemented a high quality resampler, which
simply requires more CPU power. The patch in staging turns down the quality of
the resampler if there are more than 4 buffers to resample. This kind of works,
but if I have a high end CPU, I'd rather get the high quality.

I think a smarter heuristic might have a better chance of getting in. For
example, we could time how long resampling takes, compare that to the period
length, and lower quality if a large percentage of the period is spent
resampling.

Another option is to increase the efficiency of our new resampler so it works
on older CPUs.

In any case, no such patch exists, and this problem will largely solve itself
as users get better CPUs, so it isn't terribly high priority.
