Pisound on Ubuntu-Mate 64bits

I don’t seem to be able to install pisound on Ubuntu-Mate 64bits. Is it only available for 32bits? I am getting the following error when I try to install it:

N: Skipping acquire of configured file ‘main/binary-arm64/Packages’ as repository ‘http://blokas.io/apt rpi InRelease’ doesn’t support architecture 'arm64’

Yes, it’s currently 32 bit only. We’ll add 64 bit builds once Raspberry Pi OS 64 bit version reaches maturity and exits beta stage.

The main Pisound functions should work on 64 bit OS anyway. You could compile the button daemon for button functionality and install it from source code:

git clone https://github.com/blokaslabs/pisound
cd pisound/pisound-btn
nano Makefile

# Change 'gcc-4.9' to 'gcc' in this line: https://github.com/BlokasLabs/pisound/blob/master/pisound-btn/Makefile#L26
# Ctrl+x, then Y to save and exit

make && sudo make install
sudo systemctl enable pisound-btn
sudo systemctl start pisound-btn

This should set up the pisound-btn daemon so it will react to the button interactions.
