Mac Mini 2014 problem with local/usb output to dac

Hi All
Having problem with local and USB output with Audirvana Studio.

Set up
Mac Mini late 2014 Monterey 12.6.2 to Audiolab MDac or IFI Zen Dac
AS Studio 2.2.2 and 2.2.3 just updated but both have same problem

Using UPnP output works fine to various HiFiBerry Digi2 on Pi

BUT When switch to direct USB to dac connection on either DAC AS starts song and then hangs . Have to force quit

Also hangs if just output to Core audio speakers on Mac Mini.

Running AS on Macbook air 2020 with Ventura 13.1 works fine to same two dacs

So it is a local problem on the Mac Mini.

Is the OS too old for this version of Studio as Audirvana 3.5 still works.

Tried disabling integer and exclusive and sys opt on and off - no effect

Also set to 96 khz which is limit on the Audiolab via USB, still hangs

Checked Audio Midi and is set to 96 for audiolab

Thanks for any ideas
