The card is Chaintech. 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).
