Problems with sound disruptions can usually be traced to running with
WITNESS and/or INVARIANTS compiled into your kernel. These debugging
options cause enough interrupt latency to cause sound problems.  Even
setting the sysctl debug.witness_watch=0 (I guess its
debug.witness.watch=0 now) will usually clear the issue right away, or
reduce the disruptions significantly (for that boot only).

If the sysctl doesn't exist then you don't have WITNESS.
