I have an Auro 3d demo disc which I played using the 7.1.4 test signals. These were output to the respective channels without any issues. I also played some of the demo material and could hear sound from all the channels. 11 plus subwoofer. However, I did notice that the Yamaha showed that the signal was DTSHDMA... AURO 3d. The A8A did not output to Auro 3d if the format was "Straight" or "Auto". You have to change it to Auro 3d manually using the "Surround button" on the remote. You can use the Musiccast App to do this, too. To use the Auro 3d mix settings, you'll have to use the Musiccast app. I have not noticed any settings on the A8A directly.
Can someone confirm that the A8A indicates DTSHDMA...Auro 3d when playing a native Auro 3d disc like the Demo disc (Auro 3d).
I will try to discover what else is included in this firmware. I hope the other bugs have been displaced.
