What

SlabPi is the replacement for Slab on a Raspberry Pi 3. It has been moved, because of downscaling. It will be challenged with as much infra a Raspberry Pi can handle.

It runs the MPD Server and espeak. It is running on Raspbian Stretch Lite.

A DAC+ Hat has been added for better audio quality.

DAC+

PiFi HIFI DAC+ Digital Audio Card added for better audio quality.

Installation:

Edit /boot/config.txt

Disable the line

#dtparam=audio=on

add

dtoverlay=hifiberry-dacplus

MPD

Currently runs through LiquidSoap, so there is a +- 30 second delay. Ask r3boot ;).

Fixed an issue where MPD hangs on song change. Fix it by uncommenting "device" option in the "audio_output" block (in my case ALSA) in mpd.conf. This is a common error.
