Hi, I had same problem. Turns out that it's related to screen refresh rate - setting your global setting to 60hz should fix it (can't say how, or why though) I reached out to Positive Grid about it and they told me they are already working on a fix, so fingers crossed!

If figured it out with the Fold 3. Which has weird screen sizes. I forced it to run in 4:3 in open screen folded out mode and it worked fine, no tone Disconnections. I see you're not using a Fold 3, so it won't be exactly the issue I had.but it might be a screen/display issue. Try changing some Display settings. I verified this by install the app on an older hpne with a more normal screen size and no customizations and it worked fine. So it wasn't the App or Speaker. Have you custom changed any display settings? What phone have you got?

...exactly the same problem....no fix yet

I have the exact same problem but with the spark 40. If you managed to solve it could u tell me how to do it or anyone else?

Same problem.
