I have an old Soundblaster Live card with 5.1 out (as 3.5mm jacks) that I'd like to use to connect my PC to my TV amp as optical in. I know this would require an analogue to digital converter but so far I've only found Opt in>3.5mm out NOT the other way around.
I cannot find any converter that is 3.5mm in>Opt out, Im wondering if there are any around and I'm just missing something?
You can simply replace the old card with a newer one with optical out, or use the HDMI out on the computer along with an HDMI audio extractor to split the audio out from the video that will feed into the TV. Looking for adapters that would cost the same as a full new card, you are better off just replacing the card.
