Only one channel playing after DOS2

[F_M]

I've had the same issue with my two whites. Suddenly one speaker became silent. I cut the power to the speakers but that did not help. Then I clicked three times in a row on each speaker (some kind of restart) and then set them up again. And after awhile they started to play in stereo. Long press is reinstall the whole system.
