yes. from what i think anyways. im no expert tho in audio.
just an idea of what i think u need.
my surrouc headphones have 3 - 5.1 speaker leads and 1 mic lead, plus a usb hookup for power....i have an old audigy i'm using --- if newer cards that have amplifiers only on digital then i dont think i'd see an improvement with a newer card....unless i adapted the analog to digital ? --- thaqt would seem to defeat the purpose since i believe the analog outputs on the card are more specific rather than the 'virtual' sound generated by digital??????? can someone confirm this please?????
