I searched for your system online and found its manual. I don’t know what the sound quality is like but from the specs and features, it looks like you have a very nice system. The built-in blu-ray player is a nice bonus!
A couple of questions for you:
- Your AVR natively supports Miracast, DLNA and Wi-Fi Direct. Is there any particular reason why you are using a WDA?
- As I suggested in my previous post, have you tried attaching the WDA to the tv and have the sound passed through to your AVR? I’m assuming you’ve attached the WDA to the receiver to get multi-channel audio, but most, (if not all), tvs will be able to pass through up to 8 channels of uncompressed audio via HDMI.
As for your situation at hand, from p.29 of your system’s manual regarding audio settings:
When [Digital Output] option is set to [PCM Multi-Ch], the audio may output as PCM Stereo if the PCM Multi-Ch information is not detected from HDMI device with EDID.
You didn’t mention the make of your tv, but most only carry a stereo (2ch.) decoder. It sounds like if this is set to something other than PCM stereo, your AVR will revert to your tv’s EDID and output only stereo sound. Check to see that you have the correct audio setting.
