Description

this fixes a "pcm0:virtual:0:dsp0.2: play interrupt timeout, channel dead" error
and sound breaking off after a few seconds of playback I encountered on my
Thinkpad X40. It was discussed on freebsd-current in 2004[1] but that code is no
longer present in FreeBSD while we still have it.

The patch[2] removes a line fixing a channel timeout to 1 tick instead of the
value calculated immediately beforehand, thus restoring the calculation.

Interestingly, this problem is gone for me on master even with the forced timeout.
