There is a mic boost on win7 aswell. goto control panel, then "hardware and sound" go then into "sound" Go into the tab "recording" double click you mic source. then from there goto "custom" There should be able too click on mic boost.
Yeah, i have the exact problem with bretwags. Theres no option like microphone boost. Everything seems to be fine, microphone should be connected and working, but when i talk into mic, the sound bar doesent move or anything.
There are a couple ways to get to Mic Boost in Windows 7...
Rt Click on speaker icon (taskbar by clock) > Recording Devices - you get a (Sound) window, Microphone @ the top, highlight it, hit Properties button (bottom right corner), select Levels tab.. you will (now) see 2 sliders, 1 for volume & the other for boost.
OR type Sound in Search OR > Control Panel > Hardware & Sound > Sound. End up @ same as above. So @ least 3 ways.
