I'm kinda glad I'm not the only one too.
Had mine since January 2021 and in the last 2 to 3 weeks having the same problem of no sound on all sources. I have to reboot the power to speakers for it come back, only for the same thing to happen the next time I go to use them.
Very disappointing, klipsch get this sorted ASAP please. These are premium speakers and we're expecting a quality service.
