Comment 15 for bug 1833225

Unfortunately there is no binary available for 2.2.4 yet.

I think the easiest way is to downgrade libshout:
By luck the eoan dep package can be installed
https://packages.ubuntu.com/eoan/libshout3

If you are not afraid for installing a lot of dev packages,you can build your own 2.2.4 alpha.

If you are interested in bleeding edge features and like to help us towards the 2.3 release,
you can install:

But please backup your .mixxx folder first and test all your use cases before going live
