The Sonos Amp goes into ‘idle’ mode when it doesn’t detect an audio signal for more than 3 minutes.
It’s a shame that the Amp doesn’t automatically wake up from idle mode when the TV it’s connected to is turned on. Every time I switch the TV on, and begin playing content, I miss the first 3 seconds of audio as I wait for the Amp to wake up. Every other audio receiver I’ve used has been able to turn itself on when the TV is turned on, using HDMI CEC control. Could this not be implemented in the Amp?
This problem also occurs when you pause whatever content you’re watching for more than 3 minutes - the Amp goes to idle mode, and then you miss the first 3 seconds of audio when you begin playing again. Could idle mode not be disabled when the connected TV is powered on?
