Ticking sounds, clicking sounds, call it what you will, I get these too.
I have version .169 installed. I am using a Mac Mini with 16 gig Memory, I have an Apogee Duet as my DAC (yes I know, it will be replaced one day).
The issue happened with previous versions as well. And yes switching from 16/44 material to DSD (converted to 24/96 PCM) and back to 16/44 immediately causes the issue to happen.
Let me know if you would like more information. I thought it was just me going slowly insane...
