I have one pi 3 with hifiberry DAC+ running the squeezebox server and squeezelite, and one pi B+ running squeezelite syncronised to the pi3. I am just using the headphones port for audio out of that one.
Both players work fine, except for airplay.
Both of them show up on my ios devices, and are able to be connected to. They look like they are playing but there is no audio coming out.
Is it something to do with my soundcard setttings?
I have made the shairport soundcard the same as the squeezelite soundcard in both instances. Is this correct?
For the pi3 I am using sysdefault – snd_rpi_hifiberry_dacplus and for the B+ I am using hw – bcm2835 ALSA, bcm 2835 ALSA
If you use the same output for both players, you need to utilize the feature listed in shairport’s advanced options: Shairport/Squeezelite automatic Audio-Switch
The instructions next to the feature tell you how it works and how to use it.
