Hifiberry Amp+ Raspberry Pi no sound

Hi All, I am trying to get my Raspberry Pi 3 working with Hifiberry Amp+. Everything seems fine. I have changed the output to Hifiberry Amp+ in Playback on Volumio web interface. I am playing Pandora on my laptop on the same wifi network as the Pi. I then click the airplay option on preferences on my macbook. I don’t get any errors but no sound out the speakers. I know the speakers are good because I can tap the wires to a 9volt battery and hear static on the speakers. Any help would greatly be appreciated. Please let me know if there is a better way to test or if you need any more information.

Thanks in advance

Sorry, I have no experience with using Airplay with Volumio, but you are much more likely to get some help if you edited your topic title to reflect your problem ie. no sound with Airplay & Volumio. :wink:
