No sound from Sony STR DG820 surround sound when use Benq PE5120 for video viewing

Andy Bye Oct 12, 2017 11:09AM CDT

Hi. I have a Sony STR DG820 surround sound amp. I have various HDMI inputs (DVD player, BT YouView, PC)to the amp, and have one HDMI output (there is only one HDMI output) from the amp to my Sony TV. This all works fine - I can watch the picture on the TV and listen to the audio from the amp at the same time.

However, if I then unplug the TV from the amp HDMI output and plug in my Benq PE5120 projector to the same HDMI output, the picture shows through the projector but the sound stops on the amp - i.e. the projector effectively disables the audio output from the amp!

I have read and re-read the manual and tried many options but cannot get it working.

Any ideas?

Have you contacted Sony about this? There isn’t anything in the projector that would cause this – it just passively receives a video signal.
