No Sound - The tortures of upgrading -

Upgraded to a Macbook pro M1 - ios Ventura 13.1 - New Controller AS Native I. Logic pro10.7.7
I cannot get any sound. Fine until the upgrade.
I have removed components - Re-installed version 2.7 - Validated logic plugin manager.
Is there anything else I could try?
Any ideas will be greatly appreciated during this time of desperation.

Thank you

For what its worth, version 2.72 works well for me in Ventura 13.2. I had trouble in 13.1

Hey @darrylld Try turning MULTI VOICE OUTPUT (settings/preferences) Off and then On again and see if that helps. Also download latest update (2.7.2) and let us know if problems persist.
