[FRUSTRATED] Missing Sound Codecs for Lenovo ThinkCentre M710e

[Roy Spliet]

The 4.15.0 kernel was released in January 2018. Your computer was first 
sold around May 2018 (at least where I'm from). It's hardly surprising 
that some components in your computer aren't supported. First try 
upgrading to a newer kernel (ideally 5.6) before you try other steps to 
debug your issues.
