I have a Soundblaster Z. I've been using the ports on the back of the sound card for my headphones, mic and speakers. But now only the 3rd most port works for playback now. My headphone port on the front panel and on the card don't work. It's not a problem with my speakers or headphones. When I say 3rd port, I mean the one in the middle after mic and headphones: I can't see my headphones in Windows playback devices either. Can anyone please tell me what the issue might be?
