I took a quick look, it's incorrect for dscapture and dsoutput,
underruns are already handled there in CheckXRUN, in case of _Stop it is
unneeded as well since it just stopped and restarted, no underruns
possible. The only thing needed in that part is that the < 0 checks need
to have a cast to sframes.
