I have an Auzentech HDA X-PLOSION 7.1 DTS sound card running 32bit vista and i'm having some problems. On my last computer i was able to connect my Boss ME-50 (guitar effects pedal) into the line-in to make it output on my speakers as well as being able to record. On this computer however i can't seem to make it output on my speakers as i'm playing though the line-in does seem to be picking it up. I'm new to vista and i've searched the settings everywhere and i can't figure out where the issue would be. Also as a bit of a change i'm running my speakers through an optical cable now instead of a 6-chan that i used to be though i'm not sure if that would be an issue. Any ideas would be great!
