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

[Ashley Wright]

Hi Jason,

This looks good, I have found the file and the setting "*audioInputMute: 
1" However if I set this to 0, next time the Venue Client opens the RAT 
it is set make to 1.

Also interesting, if I open RAT with the command "rat 
xxx.xxx.xxx.xxx/xxx" the mic setting is left unchanged (this is good), 
however if it is opened with the Venue Client then I still get the 
feedback. This is making me think the venue client is doing something I 
do not want it to do.

Any more ideas?
Ashley
