AirPlay is a great feature built directly in to iOS / macOS allowing music streaming to speakers and video streaming to Apple TV’s.

There are two ways to install ShairPort-Sync via the command line or the Raspberry Pi GUI. This depends on the version of Raspbian you're running.

AirPlay speakers or an HomePod can be expensive if you’ve already invested heavily in to audio equipment. As long as your audio equipment has an AUX port you can use a raspberry pi to supply wireless music to it and play it loud.

You don’t need expensive speakers or audio equipment, just a pair of powered speakers will suffice, a Aux in cable that’s either 3.5mm to 3.5mm or RCA to 3.5mm. Now the full size Pi’s have a headphone jack, the smaller Zero series will need a HAT on top to output the sound, I’ll cover one of those in the future.

To autostart shairport-sync on reboot or startup run the following command, and its done.

sudo systemctl enable shairport-sync

Starting and Stopping

To Start 

sudo service shairport-sync start

To Stop

sudo service shairport-sync stop

Other Tweaks

Checking the Audio Levels via Terminal or SSH run the command

Which opens up a display showing the current volume level, which can be adjusted using the up and down keys on your keyboard.

ESC exits the CLI Program.

If things get a bit sluggish or buggy, you can use HTOP to find out what’s going on.
