The esi gigaport hd+ is said to give 8 outs cleanly on an Rpi, search the list 
for reports from several people, but I have not tried it myself.

With an Rpi you might then use the GPIO for your IR, but if the IR stuff is USB 
then you'd have to test, and may well be out of luck. A cheaper sound card and a 
more expensive computer may be just as sensible though.
