BUG -- when I feel I'm the only person using AES 5.1 output

hello

I've been using the Decklink Studio 4k - yay 6 AES outs!

first in a High Sierra Mac - with pci-e slots
and now on a Macbook Pro 16 - running Catalina 10.15.5 - card in a Thunderbolt 3 box

Both setups are primarily meant for Resolve editing with 5.1 audio
And most part it works very well

But BOTH of these systems get used for a lot of different things
And I am finding that is the AES output gets corrupted as one moves from one application to another

It seems to be an error when there is more than one application requesting different sampling rates
So for instance if I'm running VLC
And I open up a YouTube window to find a piece of footage
(Using Chrome or Safari seem to set off these bugs more than anything else)
and then the audio system craps out

The end result is that the audio stutters and crackles
And even if I turn off the playback on all of the applications I still get remaining audio I assume from a buffer repeating

Another problem is that if you opened up the Apple App Store app
When you close it it kills all audio

It also seems that if you let the computer go to sleep for a while
And it ends up going into -- I believe hibernation - or deep sleep
(I'm not exactly sure what they call it anymore)

On awakening the audio again is distorted skipping repeating and crackly

This has been getting worse with the last three or four versions of the desktop video software
And there seems to be regressions in the feature sets
(I was at one point getting the capability to get a 96kHz sample rate in my timeline - maybe macOS fault?)

I'm currently running 11.5.1
macOS 10.15.5 - fully loaded macbookpro 16 inch (all the ram and all the GPU)

I'm aware that Apple has been dicking around with the audio output in the OS
But unfortunately the desktop video software has not been keeping up
Specifically for the AES digital outputs

I'm kind of assuming that I'm going to have to move to either SDI or HDMI embedded audio to fix this

But it's kind of a shame because the decklink studio 4K is an excellent very versatile card


thanks in advance
