I have a Sound Blaster Live! Platinum 5.1...its installed properly.no evidence of problems in device manager tab...i tried the diagnostics tool and it fails the record part. i can hear the sine signal but on playback its silent. the mic is in the correct slot. volume is up full wack...nice one
Have you tried enabling the "Mic Boost" in the advanced system sound settings? Have you ensured that the Mic is not muted in the OS sound control panel? What application are you using to record? Make sure to set your app's input device to the proper card/mic. You'll find that in the Options or Preferences. You shoulds also go to the system sound settings and make sure the audio record device matches your card. If playback is your only problem, go to the system sound settings and make sure the audio playback device matches your card. Let me know if any of this helped. Good luck.
