Before opening the issue, have you...?

Searched for existing issues

It's not exactly MonitorControl problem, but maybe you can solve it.
The problem happens with two different USB-C-connected monitors - Samsung and LG.
It shows up both with Sonoma running MacBook Pro and Monterey MacBook Pro. M1 and M2.
With MonitorControl and without MonitorControl.

If the laptop reboots while not connected to the monitor, sound through the monitor speakers will be garbled.
Videos that have sound are reproduced in a very jittery way, skipping fragments, scanning back and forth, etc.

If I reboot the laptops with the monitors connected, there is no issue, even if the machine is disconnected and reconnected later.

Describe the solution you'd like

It looks like there is some synchronization with monitors happening at reboot and at reboot only.
Is there a chance MonitorControl could do some sync to avoid this issue?

Describe alternatives you've considered

Reboot while connected to the monitor is the only solution I found.

Anything else?

No response

This seems to be some kind of hardware issue. You can try using BetterDisplay and use Tools/Displays.../Reinitialize External Displays to check whether that helps.
