How I setup Subsonic

---

Multi-room audio with Snapcast and Raspberry Pi

Clients

Justboom DAC hat

add the below to /boot/config.txt

dtparam=audio=off
dtoverlay=i2s-mmap
dtoverlay=justboom-dac

Snapclient

Do the following for each client device.

Use scp (“copy over SSH”) to copy snapclient (note the colon after the IP address).

scp <path to download folder>/<snapclient name> pi@<IP address>:

Note that you can access the C:\ drive from WSL via /mnt/c/.

Now SSH back in and install the package.

sudo apt install ./<snapclient name>

Now we need to configure snapclient a tiny bit. Modify SNAPCLIENT_OPTS in /etc/default/snapclient to add the HifiBerry as the sound device:

SNAPCLIENT_OPTS="-s sndrpihifiberry"

To edit the file in a terminal, do sudo nano (you need sudo for files in /etc/). The name “sndrpihifiberry” I found by calling aplay -l:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

If you have some other setup than the HifiBerry, check aplay -l for the name of the sound card. That’s what I did to use my MG10XU as one of the clients.

Restart the client to read the new configuration.

sudo service snapclient restart Now exit SSH.
