Hi guys, thanks for sharing informations about this issue.
It’s a complex one and in the meantime, you can revert to the 2.4.0 versions using the links below:
To everyone having the memory leak, thank you for pointing this issue, this allowed us to quickly find a fix for it.
We just deployed the update 2.5.2 of Audirvāna Studio/Audirvāna Origin for Windows/Mac which fix the memory leak

I redid my test after installing 2.5.2: I played two albums consecutively pressing the start button on the first song of each album and letting the album play to completion. I should add that all my files are Apple Lossless audio files.
After loading the first song of the first album memory usage was 962 meg. After finishing the first album memory usage was 1.3 Gig. After releasing the lock on my DAC, memory usage was 199 Meg. After loading the first song of the second album memory usage was 1.03 Gig. After finishing the last song of the second album the memory usage was 1.15 Gig. After releasing the lock on my DAC, memory usage was 210 Meg.
Thanks, development team, for such a quick turnaround.

Thanks for the quick solution! No memory leak anymore on my system.
Hopefully you did not have to stay up all night hunting the problem

System: M2 Mac mini currently running Audirvana Origin 2.5.2 (20502)
DAC: Denefrips Ares II with up to date firmware.
Connected Via USB
Further debug info below
I am not seeing a memory leak issue. OSX reports that Audirvana is using between 2.3 and 2.45 GB of memory. The library has about 32,000 tracks so the memory usage doesn’t seem out of line. This is on a dedicated media computer that only runs Audiravana and a few other minor programs.
Issue 1
On 2.5.0 I started noticing subtle ticks. I was playing 16/44.1 lossless files and Audirvana was uprezzing to 32/1536kHz. The DAC was reporting that the base sample rate was 48kHz. I shut off the uprez feature and manually set output to 32/44.1. This fixed the ticks. With 2.5.2 I reset the output settings to the DAC’s defaults (32/1536kHz) and I have not heard any further ticks. The base sample rate is still reported on the DAC as 48kHz.
Issue 2
At the ends of tracks, the last maybe 1/4 second is cut off and the next track plays. This occurs both on random track selection and playing in order off of an album or playlist.
Issue 3
The last track of a playlist does not get listed as played when the track has finished. I’ve seen others comment about this.
Issue 4
This may only be cosmetic or it might indicate some other, deeper issue, but I usually have the waveform display turned on when playing tracks. As a new track is loaded, usually between 1/3 and 2/3 of the track waveform is rendered on screen, but never the full track. As the track plays, more of the track is rendered.
