If I unplug my sound card interface, should I hear audio tones when WSPR is transmitting?

Good evening Sorry for the 'dumb' question but I've been pulling my hair out since rebuilding my old Acer laptop. I'm now no longer able to transmit WSPR - the rig is keyed but no audio is transmitted.

Unplugging my sound card interface and I was expecting to hear the audio tones that would be passed to my radio (FT-817) coming out of my laptop speaker for the 1 min 50 sec transmit interval. Nothing.

The WSPR 2.0_r1714 setup drop downs allow me to choose between Realtek HD Audio or Microsoft Sound Mapper - neither seems to work.

Poking around the C:\Program Files\WSPR files and my wspr.ini includes:

WSPRGeometry 703x549+44+58
MyCall M0HKG
MyGrid JO01EU
CWID 0
dBm 37
PttPort COM7
CatPort None
AudioIn 1#Realtek#HD#Audio#Input
AudioOut 3#Realtek#HD#Audio#output
BFOfreq 1500
PTTmode RTS

And my audio_caps file:

0 2 0 0 1 Microsoft Sound Mapper - Input
1 2 0 0 1 Realtek HD Audio Input
2 0 2 1 0 Microsoft Sound Mapper - Output
3 0 2 1 0 Realtek HD Audio output

I've tried loading WSPR up on my works laptop this evening but I have exactly the same problem.

Any suggestions?
