Thanks for the super quick turnaround. I tried the fix and had mixed results. My iFi SPDIF converter
appears to be working normally again in exclusive mode.
But the Audiophilio (my preferred converter) still won’t play hi res files. When I attempt to play a hi res album
I see all the tracks cycle through their waveforms and disappear in the space of one second. And nothing
shows up in the queue.
I’ll use my iFi for now and hope you will come up with a better idea.
Now the 44kHz 16bit files are played also in exclusive mode but there are still two strange behavior:
if exclusive mode is disabled, roon is not changing the frequency on my dac when playing files with different resolution. The frequency on the dac stays 44kHz even when playing 192kHz files (it looks like core audio is doing the down sample)
in exclusive mode when playing file with different resolution, I see that the dac is alternating 3 times between “no lock” and the new resolution. For example when switching from 192kHz to 44kHz the display of the dac is showing 192kHz-> no lock -> 44kHz -> no lock -> 44kHz -> no lock -> 44kHz and then playing the new file while before the behavior was 192kHz -> No lock -> 44kHz and then playing the file.

That’s because in shared mode CoreAudio downsamples everything to lowest sample rate.

Can’t say much at the moment about this behavior. I’ll check in with the team whether we have such DAC in house to test or not.
Regarding item 2 is there a log I can collect to help you with the analysis? Paul_Kovit reported the same behavior and he has a iFi, maybe you have this electronic in house to check?
Regarding item 1, since when the behavior is like this? I’ve been using roon for a long time without exclusive mode (don’t remember which version) and roon was changing the resolution on the device based on the resolution of the file. This is also how every other sw is doing (I just tried pure music to confirm).
