(mac osx 10.14.6)

last week I listened to music streaming when the resting state of the mac kicked in. audio stopped. ever since that occasion no audio comes from the multiface anymore. the multiface is still recognised in the HDSPe Settings and totalmix is on but there is no mixer window.

logic audio reports a sync error. it believes to recognise audio rate 44.100 while the project and the HDSPe Settings state 48.000 Hz.

when i open file > new totalmix window a dialog box appears to choose a device. the device list is empty.

i had driver x86_413 running. no i installed the latest version x86_417 but the problem remains.

does anyone have an idea what to do?
