I found a good mic to use that transmits nice and clearly. Tried it out in offline to get my buttons set the way I want them, but an issue I noticed was whenever I start or end a sortie the voice transmits for the full 4 seconds you're allowed to key your mic. This happens whether I have auto select mode on or if I manually select my mode (which I thought would have been the problem). It also happens whether I have the voice transmit key set to keyboard or my stick. I thought maybe it was just because I was in offline so I tried it again in the TA. I got the same problem there too.
I would think it would get rather annoying for other people to have my mic transmitting for 4 seconds after I start and end every sortie, so how do I go about fixing this?
