Yesterday I tried to use my headsets microphone for the first time after upgrading to Windows 7 64bit. The sound was so muted that it was inaudible. Boosting levels and changing recording quality changed nothing. After reading numerous “try this, do that” forums posts I finally found the one that worked at Windows7forums.com.
- Right-clicking your volume control icon
- Go to “Playback Devices”
- Click the “Communications” tab
- set it to “Do nothing”
On a side note, Windows 7 seems to include so many checks and balances to keep sound volume in balance that the microphone gets almost muted.
