Follow-up, and bug can be closed, hardware issue. For the record, I do think that the frustration in the original bug report does point out that there is a need for a low level testing tool, to help identify if it is an actual hardware issue, or a problem with detection, or the drivers etc..
Out of frustration, I ended up calling the vendor (Lenovo) and while I haven't been happy with their hardware historically, and don't laugh that I ended up buying a ThinkCentre for a Linux station, I was pleasantly surprised with their support. I was able to get a hold of a human almost right away, but I do think that Lenovo has a known hardware issue, that they only tell people about if they call for support. AS soon as I mentioned 'audio' problems, he surprised me by not questioning it at all, and that 'they would send a technician out to replace the motherboard'. (I thought he would at least put me through a testing song and dance, but no, no questions asked.. 4 minutes later off the phone) Took about 10 days, but true to their word, motherboard was shipped, and technician showed up, replaced the motherboard, and all sound devices detected on boot, immediately. (No changes need to sound configuration) I guess it passes the hardware compatability with 16.04 ;) Thanks all for your comments though.. but consider that some form of 'testing' tool, should have come to the conclusion this was a hardware issue and saved me a few days of learning low level alsa/sound.

This is a Think Centre M710e Model/Type 10UR, and the snd_hba_intel correctly loads, but finds no codecs. This is the onboard audio card, and don't think they have chnaged it much in years, so I expect that at least SOME codecs should be detected.
