I've had my AIOS extender for about a month now, and it's been great. The damn thing actually convinced me to setup a 5.1 system for the first time since the late 90s.
My issue is popping from the speakers when a 5.1 source is paused or the stop button is pressed. The HDMI output on the AIOS is set to RAW. In the same menu (Audio), LPCM and LPCM Multi-Ch settings both result in 2.0 output (as shown by the receiver's display).
probably the salient point: When I press pause on the AIOS, I can see on the Onkyo TX-NR509 display that 2.0 is now the audio output mode. I press pause again to resume play, the speakers pop again and the display shows 5.1 mode.
The Onkyo menu under Setup > Source Setup (option 8) > Audio Selector, it's set to HDMI and fixed mode off. Every other option there results in no audio, and a flashing HDMI on the display. The other options are:
If there's no hope, that's fine. But I'd like to know if it's me doing something wonky with one of the settings that's causing the popping. I found a thread for a TX-SR606 elsewhere online, and it mentioned Listener Mode under Setup, but I can't find that in my menus.
Thanks for any help!
