Microsoft Surface Pro 7 audio gear setup

[StuartR]

I have a Microsoft Surface Pro 7.  I am trying to set up JamKazam using just the built in mic and speakers.  My Audio Input Device list is:  

Headset microphone (@System32\drivers\...) 
Headset microphone – WDM;  
Microphone Array 1 (Realtek HD Audio Mic input with SST)-WDM;  
Microphone Array 2 (Realtek HD Audio Mic input with SST)-WDM;  
Microphone Array 3 (Realtek HD Audio Mic input with SST)-WDM;  
PC Speaker (Realtek HD Audio and output with SST) – WDM;  
PC Speaker (Realtek HD Audio output with SST) – WDM

Output Audio Device list is:
Headphones 1 (Realtek HD Audio and output with SST) – WDM 
Headphones 2 (Realtek HD Audio and output with SST) – WDM 
Headset Earphone (@System32\drivers\...) 
Speakers 1 (Realtek HD Audio output with SST) – WDM 
Speakers 2 (Realtek HD Audio output with SST) – WDM

Regardless of what combination of input and output devices I select, I get the error message “It appears this audio device is not currently connected.  Attach the device to your computer and restart the application, or select a different device.  If you think your gear is connected and working, try a different sample rate.”

I would greatly appreciate some help.

Other info:  Surface Pro 7 has USB 3.0 and USB C ports, and a combo mic/headphones jack.  No other apps were running when I attempted the JK setup, and I followed the advice in another post to go to Sound Control Panel and turn off "allow applications to take exclusive control of this device" for speakers and mics.

Short answer... Don't bother. The Windows WDM drivers are typically not suitable for real-time audio. Try installing the free ASIO4ALL driver and see if the latency is reasonable. I'd guess however that you'll need to get a real hardware audio interface.
