how to? 2 optical in to 1 optical out?

[Guest]

i have a astro a40 headset, which has a mix amp that has an optical connection, normally you would take that and plug that into a pc then the pc sound would go to the headset.

my question is how can i get sound from 2 places at 1 time to go to the headset. i want sound from my pc and my TV (which both have a optical connection, however my headset only has 1 input.

i looked at a splitter but they only do output connections and not incoming sound.

some have mentioned a switcher, BUT i want both sounds at the same time. and a switch only allows 1 sounds at a time.

what can i do? any help would be severely appreciated `
