2023.3 Aux IO/Dolby Audio Bridge Issues

[MPizzaMusic]

Working strictly with music, I've been using HD Native as my main playback engine and then using the Dolby Audio Bridge output as an Aux I/O to send to the Renderer. Have had no issues on 2022.12, on this new version I get constant -6172 errors telling me to increase buffer (already maxed out,) remove plugins (happens with no plugins) or make sure clocking is correct (it is, using single MTRX Studio working at 48k.) Like I said I've had zero problems on the last version of PT, this is new issue that has come up since updating to the latest. Happens on both Rosetta and Native.

I first noticed this issue because I had to make an additional edit to a project that was started and completed on 2022.12 last week. When I reopened on 2023.3 it worked fine at first, but after a resetting my computer the issue started and hasn't work at all since then, even on blank sessions.

Running Mac Studio (M1 Max), 64gb ram, 12.6.2, PT 2023.3,MTRX Studio, HD Native TB

EDIT: I just downgraded to 2022.12 and it's working perfectly, so it seems like a 2023.3 bug.

A friend of mine is having the same issue with HDX as his main playback engine and SSL BiG6 as an Aux IO, so it may not be limited to the Dolby Audio Bridge.

Has anyone else experienced a similar issue?

I have severe 100% cpu problems using pro tools 2023.9 on monterey 12.7.1
The release should be supported. The problem occurs when using PT in HDX and sending signals to the DAR via Aux i/o
In activity monitoring there is the coreaudiod which crashes at 1000% making playback impossible
I tried playing the same project using the Dolby Audio Bridge directly without using the aux I/O and the problem disappeared. But I lose the enormous advantages of using the aux i/o
Has anyone had the same problem and solved it?
