It's probably worth supplying the output from pulseaudio -vvv (you may 
have to run pulseaudio -k first) in order to see what debug output is 
listed when you get the skips.

I presume you also hacked up your default.pa to get the optical output 
working so posting that would be wise too :)

It may be that you do not have realtime privileges or perhaps you're 
using some proprietary drivers (e.g. nvidia graphics) which can mess 
about with the timing in the kernel (although I believe that this 
affects pulse versions post 0.9.10 more severely than the 0.9.10 that 
shipped with 8.10 AFAIK).
