I’ve setup a Raspberry Pi B with Shairport to AirPlay music to my speakers. Works a treat, however the audio quality is poor and volume is low. I’m therefore looking to add external sound to fix both these issues.
Also considering replacing the Pi B with a Pi Zero.
Problem is I’m also using GPIO to turn my speakers on and off via a relay.
I was wondering if the Pimoroni pHAT DAC used all the pins? If not, which ones are available for other use?
Thanks for you help!
