Hi Scott,

Thank you for the links.? Great information there.
I did end up finding the setting that was causing me the problem. The
stutter affected profiles had lower Buffer Size and Sample Rate settings
in VAC1.? I set them to 2048 and 192000 and the transmitted audio is
nice and clear now.

So much to learn about how to optimize the transmit audio! :-)

Michael,

I recommend you go through your settings and groom everything for 48KHz
audio sample rate. This document is getting a little dated, but should be a
good guide:
