[Elecraft] Using K3S Built in Sound Card for SSB Transmit

[Tom-KQ5S]

I am wanting to use RCForb (remotehams) while I am away from my rig.  I
plan on running the server on the computer connected to the K3S.  I would
like to do this with no additional interface other than the built in USB
sound card. If I set up the server with Speakers USB Audio CODEC as the Tx
Audio to Radio will this pass the audio from the client to the radio either
via VOX or by me pressing the Transmit button on the client.

I have set up the system as mentioned above and have the receive audio from
the rig going to the client on my remote computer.  I do not have a
microphone headset for the remote computer yet and before I buy one I would
like to make sure that the codec will pass the client audio to the radio
while in SSB mode.  I think I might have read where the CODEC does not work
in SSB mode but only in one of the data modes.
