sudo dnf install openal-soft.i686 openal-soft.x86_64
Now we need to point steam to use these more up to date vershions of open al
To find where dnf installed our files we can run:
rpm -q --filesbypkg openal-soft.i686 openal-soft.x86_64 | grep libopenal.so.1$
On fadora 26 I got:
openal-soft /usr/lib/libopenal.so.1
openal-soft /usr/lib64/libopenal.so.1
