(Get the code!)
Indeed my conclusion was wrong because I mixed up the versions. The bug does affect some newer versions although it seems that it was solved in the meantime before reappearing again.
To correct, I observed the following:
* The bug does NOT affect kernel version 4.18.0-15 (Tested using a Live install of 18.04.2)
* The bug does NOT affect kernel version 4.20.17-042017 (Tested on my install of 19.04 with a manually installed kernel)
* The bug DOES affect kernel version 5.0.0-13 (Tested on my install of 19.04 with a manually installed kernel)
* The bug DOES affect kernel version 5.0.0-15 (I used this version when I filed the bug report some days after I installed Ubuntu on my laptop)
* The bug DOES affect kernel version 5.0.0-16 (Tested on my install of 19.04 with an update from disco-proposed using apt-get)
* The bug does NOT affect kernel version 5.0.1-050001 (Tested on my install of 19.04 with a manually installed kernel)
* The bug DOES affect newly build kernel version 5.1.5-050105 (Tested on my install of 19.04 with a manually installed kernel)
I conclude, that the bug was introduced between 4.20.17 and 5.0.0-13, then solved between 5.0.0-16 and 5.0.1 only to be reintroduced in the most recent build (5.1.5).
As you might notice, I am only a user, so I have limited skills. The change might also come from something else but I did not purposely change any setting or behavior while I tried the different versions. I tested the sound using the button in the sound-settings of Ubuntu and Spotify (both after a fresh boot and after suspend).
