Why do you think these issues have nothing to do with drivers? Apart from confusing controls, all of these can be attributed to hardware and driver quirks.
All of the following is speculation on my side and just stated as fact for easier reading / writing.
Because through the years I never had problems with plain Alsa on the same hardware
Because it did not allow for the functionality that exposed those bugs (as in PulseAudio provided features that should work according to documentation, but didn't)
I don’t have problems with pipewire either on that hardware.
Because these bugs got fixed after PulseAudio exposed them.
Have it your way dude, I ditched PulseAudio for PipeWire over two years ago (see my post at https://www.reddit.com/r/linux_gaming/comments/kufrmu/pipewire_audio_is_so_good_now/) and never looked back. But I strongly believe that PulseAudio, despite its flaws, was an overall gain for Linux audio and I dislike people bashing the work of others.
