I run into this on uniprocessor under 3.x with both yds(4) and
previously the auvia(4) device it replaced.  it's a buffer
synchronization issue.  I can force it on my machine by suspending
(SIGSTOP, ^Z) and then starting (SIGCONT) an audio process.  depending
on the buffer states when the process was suspended, it may start back
up in an "off-by-one" state.

as a workaround, pause and start may reset the buffer and get things
going again.
