Local playlist on android not played on Yamaha Amplifier

[antonioki]

Hi All.

I've a premium account, generally with playlists generated from online music on my android phone i've no issues to play them on a Yamaha Aventage RX-A2060.

Yesterday I've created a local playlist on my computer. Downloaded and synced it on my Android phone, it plays normally with his speaker. When I select the amplifier there is no soud and on amplifier nothing is shown (track name, ecc), at same time if I switch to another playlist all is perfect.

The amplifier and phone are on same wireless LAN.

The firmware of amplifier is the last: V1.31

The spotify app version is 8.4.26.770.armV7

Thanks in advance for your replies.

Antonio
