I just heard it's not a bug, but M4A audio files currently are decoded via Quicktime thus it would need Quicktime Player or Quicktime Alternative to be installed and Quicktime support enabled via Options/Preferences/Deprecated Features.

I enabled the Quicktime plug-in this way ("Deprecated Features") and now M4A audio plays fine again in VP17.
