Description of Issue
TEAC UD-501 running in exclusive mode with CoreAudio, will sometimes stop playing any track if it is of a certain base multiple. (Say it will play multiple of 48,000Hz, but not 44,100Hz, and will even do the reverse on other occasions).
Sometimes, usually when this happens on the initial launch of the Roon client, the issue will resolve itself if I play a track that is of the multiple it will allow to play first, then alternate back and forth afterwards.
However, lately it has been doing it constantly.
It’s important that I maintain exclusive mode, to get the best performance out of the system, but resolve this issue as well.
One thing worth mentioning. If upsampling is turned on for max PCM rate (power of 2), this issue does not seem to occur.
Just as much, I’d like to avoid being limited to always upsample as I prefer no digital filters end to end if possible.
I’ve tried several small tweaks, but am possibly missing something wildly simple here.
I’m open to any possibilities to resolve this without compromising sound performance.
As I’ve cited in my original post, I’ve been able to work around this by using the integrated upsampling DSP, but I’d prefer not to use it if I can avoid it.
In regards to the integer mode, I remember seeing that as a toggle option in advanced device settings.
Not sure if this can be switched in the ARM MacOS particularly, but I will investigate and report back.
