I also have this issue.
I used d to have in in 2018, and the service center even replaced my mobo after replacing my amplifier... but it turned out to be software related.
The problem went away for a year, until the latest update.
It gets more frequent over time until I reboot the infotainment computer. I expect it will creep back in after reboot, but time will tell. I hope it's completely fixed on the next update.
