Same issue as other stated. Have the cinema 600 with the surround 3s. Setup, 65” Philips android tv. Optical connection. Currently using PCM to get stereo output through all the speakers. When switching to Dolby digital, my surrounds completely turn off. Only time I notice them working correctly is when I’m watching certain dvds/blue rays. Watching standard tv via roku, does not output 5.1 signal. I’ve contacted klipsch via email two weeks ago, no response yet. Received a general email from
klipsch last night,
Due to heavier than usual traffic, we are a little slower in our responses, but we have not forgotten about you! We will respond as soon as we can, and apologize for any inconvenience.
Hopeful for a firmware upgrade to resolve this issue soon.
