For me it was mainly this!

My Bluetooth headphones kept disconnecting randomly and the microphone never worked properly, no matter how many conf tweaks I tried.

I installed pipewire in anger, expecting nothing and it magically solved every issue.

Yes, my headphones are not expensive devices, but looks like that wasn't the problem, pulseaudio was!

I sent them some money out of happiness and now I am lobbying for it at work.
