Hi everyone, this is my first posting here, hope it is not yet solved anywhere...

I downloaded three native games for Linux (Prince of Persia, Ambermoon Advanced, Telwynium; links below) but (with Devuan 4) there is no sound in all three of them and the latter is running way too slow and choppy.
Any experiences or ideas with this?
