[FRUSTRATED] Missing Sound Codecs for Lenovo ThinkCentre M710e

[Michael]

It isn't that I can't install a new kernel, just easier to keep packaged 
versions on machines, so I don't have to track any security updates in 
the kernels..

But figured there SHOULD be some way to debug how codecs are detected, 
wanted to understand HOW the internals work better, and hopefully 
without crawling through kernel sources..

Thinking there should be some user land tools to replicate how the 
kernel internals identify codec related things, rather than just 
randomly trying alsa module configuration items.
