[WT-support] Fw: Mic/Headset not muting

We will give defining a PTT port a try but the other 5 computers have not
had one defined thus far. All Windows sounds are completely turned off, so
that has never been a problem. However, this is the only computer with a
combined line-in/mic plug.

Thus lies the issue that there aren't separate line-in/mic plugs. Upon
plugging a cable into this jack, the computer prompts us whether to choose
to use this jack as a line-in or mic device. Mic has always been selected
and is always selected in the Recording Control settings. (I even tried the
front panel mic with no success). The Input Monitor seems to have ALL the
effect on the mic, as even checking "Line-In" as the recording device
yields the same results.

Input monitor checked: ALL audio goes through the mic even while playing an
F key message
Input monitor unchecked: ONLY F key messages are transmitted, PTT audio
does not work unless input monitor is re-checked

I didn't think to check the "Mute" box under the mic slider while

We will have to check the exact model of the computer, but the soundcard is
a SoundMax (as I recall). Thinking back, the computer model may be a Dell
Optiplex 755.

I think what Bob meant by "new XP system" was that it is new in the shack
system. The computer was only installed at the beginning of this year but
was used previously for some years by one of our ops.
