Cakewalk - Audio stops then starts intermittently

[MAKARA]

The issue -

My set-up -

 

A)   M-Audio midi controller (Oxygen Pro Mini) controls my Behringer Pro 800 synthesizer - both connected via USB to my PC - and the Pro 800 synth is connected to my Fender Mustang GT-40 guitar amp - no issues on Cakewalk with those three working together nicely

- it is the top-most track "MIDI" in the video link

 

B)   My Yamaha PSR EW-425 Arranger keyboard controls the other instruments

 

- i.e. Kontakt "Komplete Kontrol"

"Synth 1 Librarian" x 2

"RT 7070" Drum machine (which is a lovely free substitute for the Roland 707 Drum machine I found today)

 

For some reason - on Cakewalk the Audio as you will hear in the video cuts out for a few seconds every so often

(I've only activated the Drums here to make it easier to hear the Audio drops - but the same issue is with the instruments in "Komplete Kontrol" / and the Tones in "Synth 1")

 

I've googled for various fixes - none of which cure it

 

Also - I am using the "ASIO Link Pro Tool" as the ASIO driver - as without that "OBS Studio" doesn't detect the Audio from my Yamaha keyboard - and Cakewalk doesn't like "ASIO4ALL"

 

Any clues as to what might be causing that intermittent drop of Audio - and how to fix it?

 

Note - I am NOT using my M-Audio "M-Track Duo" USB Audio interface - as having that switched on causes Popping and Stuttering in "OBS Studio" recordings

- so the Yamaha having its own ASIO Soundcard and Speakers is effectively the Audio interface

 

Many thanks
