Sonos Play 1 replacement: Software

Raspbian installation

Get I got a raspbian buster image (Download) and installed it on a SD card. Before booting, I modfied the config.txt in the /boot directory. Most important is to include the software driver for the Hifiberry
dtoverlay=hifiberry-dacplus
dtoverlay=i2s-mmap
Download config.txt

It is also important to activate the ssh daemon to access your raspberry. Just add a file named ssh.txt in the /boot directory. Editing the wpa_supplicant file gives you access to your Wifi.
