I am using window 7, and real tech sound manager. and my mic is not working, i found a solution that, if changed my speaker configuration to 2ch speaker then it will work. but the problem is, when i choose 2ch speaker from 6ch (i think default) in the drop down menu, it works but there is not a single option to save changes, and when i close it by only selecting 2ch speaker it does nothing. i.e when i again open real tech sound manager the speakers are set to 6 ch, anyone with solution, i just want to change 6ch speaker from 2ch in realtech sound manager.
