I am using the SB522A Slim Soundbar with a P2423DE and C2422HE with a PC and a MacBook Pro. It works fine but has the problem described above. For the Windows PC, there is a solution described below:

Microphone Intermittently Drops on Dell Peripherals Connected to Computers Using the TGL CPU
(Pro Stereo Headset WH3022, Speakerphone SP3022, and the SB552A Soundbar)

Is there a solution proposal for the MacBook Pro?

Thanks
