John,
FYI
In my case moving from 5.4.2->5.4.3 kernel broke sound on legacy nvidia systems with HDMI audio.
Interesting is that exactly the same legacy nvidia systems with SPDIF are ok.  
Issue is 5.4.3 kernel regression.
Maybe in Your case 5.3.15->5.3.16 also has regressive commit which breaks 5.4.3?
Pls try to downgrade only kernel to 5.3.15 and see….
