Acer GM712 Problem with optical out sound and CEC

I have an Acer GM712 projector and I have a problem because after connecting the speakers via the optical connector, the sound plays on external speakers but also on the speakers built into the projector,

I also have a problem with HDMI cec, the projector does not turn on or off devices connected to HDMI via cec
