It would help if you would post the make & model of the AV receiver. If it's new enough, it can stream from your phone, as I posted. If you read the manual, you may see something about a NET/USB input (Denon and Marantz have this) and/or DLNA. If you see DLNA, go to the Google Play store and download All Play or Play To, if you don't already have them- it lets you stream to the AVR in a way that's very similar to AirPlay and you wouldn't need to connect a cable or buy anything.
