I hear clicks throughout playback of DSD256. I am playing the DSD256 files on my MacBook Pro running running macOS 11.7 with 16 Gig of memory. The DAC I am using is the Macintosh DA2 on a Macintosh integrated amplifier. The files were downloaded from NativeDSD. Any ideas as to the culprit of the clicks and how to eliminate them?
Do the clicks happen randomly or at a specific time in the file(s) ?.. Initially, try dropping your output volume in Audirvana Studio -3dB… see if this clears the clicks… Otherwise post your debug info here (remove your IP address, etc)
I dropped the volume -3dB and I still hear clicks. The clicks are heard randomly and are low volume. I have used several DSD256 files from several sources. Here is the debug info:

What happens when you remove Soundflower and BlackHole, the PTools aggregate device and the Zoom device, from the signal flow and use a simple Audirvana to the DA2 set-up/configuration?
I removed the extra devices including Zoom Audio and Microsoft Teams and still have the clicks.
Please post the debug info showing the conditions with the simple Audirvana > D2 configuration.

put your memory buffer at 13000 instead of 3988

@RunHomeSlow is giving you good advice to increase the pre-load buffer allocation… However, you don’t have a clean audio path with Apowersoft and Cycling '74 and Soundflower… Also try disabling ‘integer mode’… it really isn’t buying you anything… and try limiting the bit-depth to 24 bits.
The least memory a new Apple Silicon-based Mac comes with is 8GB…
This article may help you get a picture on your RAM usage when playing those files:
Check out “Part 2. How Do I Know if I Need More RAM Mac?”
11.2 MHz DSD256 is a data hog in DoP1.1… very large files to buffer… You could try native DSD256 playback if your DAC supports it… make sure your network is capable of transmitting the high-sample-rate packet density without choking… maybe this is a network issue…
The Audirvana Studio “process” is using approximately 2 GB of system memory, In my case, where all PCMxxx and DXDxxx, is processed using an HTRF virtualization plug-in for headphones, that is subsequently up-sampled/modulated in SoX to DSD128 .
The problem has been resolved or has significantly been diminished. I am not hearing as many clicks or any at all. The extraneous sound devices (Apowersoft, soundflower, cycling, etc.) were removed. I had removed them but not completely and had to remove the Apowersoft*.k file from the shared folder.
I increased the buffer size and didn’t observe any improvement.
My MacBook is 2014 with a 3GHz Intel i7 processor and 16GB of memory.
I do not hear any difference in sound quality between DSD128 and DSD256. I just did not expect DSD256 to sound worse than DSD128! This was purely a technical exercise.
Audirvana and Roon players had the DSD256 click issue. Both no longer have the click issue once Apowersoft was completely removed.
I suspect the root cause of the issue is processing power of my Mac and the macOS.
I am going to test with a Windows PC in the near future to test DSD256 and DSD512.
Thanks to everyone for helping - especially Agoldnear and Runhomeslow!

It is most likely due to how those audio-routing applications interfere with Audirvana and Roon API’s on the Core Audio path and memory allocation and the SDD/HDD storage transfer throughput/speed demand… I believe you need a very clean and fast playback platform for flawless DSD256 and DSD512 auditioning.
Unless you are a producer or recording engineer working in the DSDxxx realm, DSD sample-rates above 5.6MHz DSD128 just don’t make sense… The Nyquist frequency of a 5.6Mz signal is 2.8MHz ! … My DAC does not allow application of it’s FIR filter options at this sample-rate because the Nyquist Fs is so far out of the range of human hearing! … As an archival medium DSD256 or DSD512 sample-rates is questionable, they are data-hogs… However, given these recordings exist, albeit very esoteric and limited at best… if the production is done natively at 11.2MHz or 22.4MHz it has the potential to capture a very focused recording of an acoustic performance that can be modulated to DSD128 with great fidelity… I personally find that trying to modulate PCMxxx or DXD to DSD sample-rates above 5.6Mz is pointless…
