So I had sound until recently, but I can’t seem to get it working now. I’ve tried to different mics and have tried looking into the game settings and my computer settings and can’t seem to find the problem. Other than StarCraft 2 saying I don’t have a mic. Everything else seems to work with sound fine, just not Star Craft.

StarCraft II seems to have a problem with 7.1 sound, so players should set their speaker options to 5.1 or lower to avoid the audio not playing properly. Another sound issue is connected to changing the OS speaker mode while running the game in Windows Vista or Windows 7. This will halt all audio playback as a result.
