Resolved with kernel-5.11
Present in march kernel test day kernel-5.11.3-50.fc33 (also reported in Test results)
Curiously enough, when restablishing dtparam=audio=on in config.txt with kernel-5.11.5, sound is working again, while that precise parameter was not needed with 5.10.3 Sorry for the confusion

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
