Thanks.
On my iMac it always showed me 3 drivers the 2TR, Thunderbolt and Thunderbolt High Precision which is the one I knew Steinberg were working with Apple on to resolved.
I have updated all to current under Monterey but have only just noted the disappearance of the Thunderbolt High Precision in the Mac Audio panel. As the Thunderbolt driver goes up to 384 in its control panel now Im assuming the high precision now incorporated. Will test soon as the Christmas rush subsides lol.
Thanks again for response.
Cheers
