Tommy,
        I'll validate the exact settings this weekend.  I don't remember
how I had the audio routed to headset since I was not using the them for
RTTY, but speaker was set to Both.  I'm running FW 1.371.  We're speaking
of the volume out of the pin 4 Accessory jack connection, "Left Aux Out".
 The speaker volume didn't change, just the pin 4 output level.

        73,  Duane
