Hello, I'm completely new to this forum and I hope that this is the right place to post this. I recently got a Soundblaster Audigy FX V2 and the Dbpro expansion card, the Audigy card works fine everything from the jacks on the card itself to the front panel audio on the PC case which I connected to it but the issue I'm having is with the Dbpro card. The digital audio S/PDIF show's up fine under audio settings so I assume that that part is working but what I really got it for was the side out jack sense I don't really use the other digital/optical audio, when I plug my ear phones into the side out jack on the Dbpro expansion card I get no sound at all and it doesn't even appear as if anything is being plugged in. Like when I plug into the Audigy FX V2 card directly or the front panel connection's it automatically switches over detecting the connection but nothing when I plug into the side out jack on the Dbpro expansion. Am I mistaken that headphones or ear phones can be used on this jack or is it something else, any help would be appreciated as I've searched online but haven't really found any help or answers. Thank you in advance.
