Hey, ive installed this driver too on win 7 on my 1602, and yes the mic is activated now, but even when the mic volume is on full 100 percent and even when you yell to the mic it does only capture on a very low level, nearly not to hear.
I thought ..ok, lets turn the mic booster function in sound setup on, but *oops, there is none. ^^
So, how can i actually make this mic record on a louder level ? Greets.
