Set AUDIO_BLK_MS=4 - unlikely to cause significant overhead on non-m68k.
Several of us have been setting this in /etc/sysctl.conf for months, to
get better performance from applications that require synced audio, etc.
It's also mentioned as a good value with low overhead on most archs here:

We could probably go lower, but this is low enough to make most/all
software run well, removing frame drops. It's also low enough to get
emulators/mednafen to stop complaining in the console.
defopt AUDIO_BLK_MS
Follow amd64 and set AUDIO_BLK_MS=4 by default
defopt -> defparam (oops)
