[AG-TECH] Problem with mic, rat and gentoo

[Ashley Wright]

Hi Jason,

This was the first thing I tried, I prefer the talk to start muted, 
however the setting made no difference.

This is a strange problem. I have had a look in the AudioService script 
(inside AudioService.zip) but cant find anything I would think would 
make a difference.
