The best is to key PTT via the serial port either use RTS or a
command. most good digital programs will do this for you. I use
VSPE so that I can use serveral programs at once that access the
serial port that controls the rig like MMSSTV and logger. and RTS
and DTS will pass through these just fine.
If you accidentally send one of the windows sounds or any other sound
like DX cluster alert sounds through the rig you are possibly
disrupting the other digital signals and as well for many reasons
breaking the law. so be sure they are off or not using the card
connected to the rig.

The major problem with using VOX for digital modes is that often hams
forget to turn off Windows Sounds and end up transmitting those sounds

hear it.
If you are using the internal soundcard, turning off Windows Sounds is
the only way to go (or do not use VOX).
If using an external soundcard, make certain that external soundcard
is
*not* set as the default soundcard for the system (Windows normally
sets
the most recently added soundcard to be the default) and then tell
your
digital application to use the external soundcard.
