Hi Matteo
I have tested on Volumio2, and you can build the last version of cava before libiniparser was unbundled with the following commands (make sure you don’t already have a cava subdirectory)
git clone https://github.com/karlstav/cava
cd cava
git checkout -b cava_with_iniparser 03a8c85c
./autogen.sh
./configure --disable-input-portaudio --disable-input-sndio --disable-output-ncurses --disable-input-pulse --program-prefix=mpd_oled_
make
sudo make install-strip
Adrian.
