Can't listen to HDMI sound on STR-DH510 receiver in "headless" mode / with projector off

[popbox]

Hello Sony community, I have a STR-DH510 receiver. It receives HDMI input from my computer and has HDMI output via the TV port to my projector. It plays audio from my computer very nicely when I am watching a movie. However, if I play a podcast and turn off the projector the receiver stops playing audio. To get audio playing again I have to reboot everything (receiver, computer). My question is, what is the correct setting to play HDMI audio in "headless" mode (without a TV powered on / connected)? I have played with the HDMI menu options but nothing seems to work for me. Thanks in advance for your help!

Hi popbox, 

Welcome to the community.

I'm not sure why this is happening, so it would good to contact Support about this here. 

Thanks,
