high interface latency with Scarlett 2i2 on Mac mini

[Chris Frost]

Is anybody able to get acceptable latency using a Mac Mini (2020) and a Focusrite Scarlett 2i2?

Hardware:  new 6 core i7 with 16BG memory and MacOS 10.15.6
Focusrite Scarlett 2i2 third generation
Jamkazam latest release, latency patch installed, frame rate at 1

Best I can get is 17.9ms for audio interface latency with focusrite.  I can get down to 7.9ms with 4 year old Presonus Audiobox i2. Still not quite usable, but better

Bonus question - any idea  why the performance of the Scarlett and the Audiobox would have been almost exactly the opposite on the MacBook pro (2015) I was running before? Core audio performance on the Jamkazam interface is green.

Focusrite support has responded but has nothing to offer so far.

Do you still have access to the MacBook Pro? .... can you check what your settings were on that (or from someone else with the same kit).... and then set your Mac mini settings the same way?

General advice for focusrite appears to be ‘96k sample rate 1ms frame and fiddle with the buffer size to get latency as low as possible’. .... that works well with mine (but I use windows).  Good luck
