Does anyone know how you adjust the mic sensitivity on HTC EVO?

Thanks!

 

Yes, actually using Vlingo and need the microphone to pick up better. If I talk directly in the phone it works fine. If the phone is approximately 3 feet away from me and I'm not traveling down the road, the mic picks up well. However at highway speeds it does not. My blackberry was MUCH better and did well at highway speeds.

 

Unfortunately, the Audio Manager has no functionality to adjust mic sensitity. I did find an application called gStrings that actually does adjust the mic in their app.

Thanks for everyone's suggestions! You would think that Sprint or Android would have this covered.
