Thanks, David. I installed PC-BSD 9.1 into a VirtualBox VM and am able to
reproduce this.

Looks like the problem is it takes a long time to cancel previously playing
sounds when a new sound asks to be played:

17.594:0009:trace:winmm:MULTIMEDIA_PlaySound pszSound='0x153278' hmod=0x400000
fdwSound=00000005
 ...
 17.688:0009:err:winmm:MULTIMEDIA_PlaySound returning control

That's nearly a full tenth of a second between invoking and returning from
PlaySound.

Jörg did work in this area recently. The code is still pretty messy, so there
might be further improvements. For example, maybe we can avoid waiting for the
other sounds to stop playing if SND_ASYNC is given.

(By the way, the "Invalid null command" is because PC-BSD uses csh as its shell
by default. You can run "bash" first and then the debugging command to generate
a log.)
