You should be able to fix it by using a bigger buffer. To do this,
change line 48 of src/sys/dev/sound/pci/emu10k1.c from:

#define EMU_DEFAULT_BUFSZ       4096

To something like:

#define EMU_DEFAULT_BUFSZ       8192

and recompile the kernel/modules. If this doesn't work, you can also try
using an even bigger buffer size, such as 16384, but then, you will have
a noticeable delay between the time you press play and start hearing the
music (it shouldn't be too bad, unless you play games).

Bye.
