ES9023 sound card setup

Configure device tree overlay file

To do this, you must edit /boot/config.txt and add the following line

dtoverlay=hifiberry-dac

Configure ALSA

Create /etc/asound.conf with the following content:

pcm.softvol {
	type softvol
	slave.pcm "plughw:1"
	control {
		name "Master"
		card 0
	}
}

Reboot your Pi and make sure device shows up.

$ aplay -l

Look for card { id }: sndrpihifiberry.

Initialize mixer

$ speaker-test -D softvol -c 2 -t wav

Installing shairport-sync

The following is taken from the install instructions located at https://github.com/mikebrady/shairport-sync/tree/development.

$ git clone https://github.com/mikebrady/shairport-sync.git

$ git checkout development
$ autoreconf -i -f
$ ./configure --sysconfdir=/etc --with-alsa --with-pa --with-avahi --with-ssl=openssl --with-soxr --with-systemd

$ make
$ sudo make install
$ sudo systemctl enable shairport-sync

Now, edit this file:

sudo nano /etc/shairport-sync.conf

Change these values:

general = {
	name = "whatever you want!";
};
alsa = {
	output_device = "hw:0,0"; // (or whatever number card,device "sndrpihifiberry" is above)
	interpolation = "soxr";
};

If audio is underflowing, set audio_backend_buffer_desired_length to 22050.
