I did a search and was not able to get any threads on the alexa connecting to a avr. I believe it should be possible to connect through the wifi router and have the alexa come up in the network similar to the media player with my PC. The other way would be to use an external blue tooth receiver and have alexa connect to that. Problem is that the blue tooth needs line of sight, if I brought the alexa outside it would be difficult to use. Hopefully someone has done this, thanks.
