Please explain these AL lib messages to me, is this relevant for anybody?

AL lib: (EE) AddFileEntry: Invalid header in /usr/share//openal/hrtf/default-44100.mhr: “MinPHR02”
AL lib: (EE) AddFileEntry: Failed to load /usr/share//openal/hrtf/default-44100.mhr
AL lib: (EE) AddFileEntry: Invalid header in /usr/share//openal/hrtf/default-48000.mhr: “MinPHR02”
AL lib: (EE) AddFileEntry: Failed to load /usr/share//openal/hrtf/default-48000.mhr

Could I have prevented this by installing monogame correctly?
Should I reinstall my audio drivers?
I had an issue where sounds did not play anymore and I fixed it by restartin my laptop, last thing it said was AL lib crashed due to too many sound instances…

The way I set up my game, that cant be, the instances wont survive out of scope… Thanks for your feedback!
