Public bug reported: I have this bug also if I install pipewire manaully on focal and jammy.
I use a Java Application using the javax.sound package to get a output to the AudioSystem. I have an own Java library using the same and I poked around a bit: It uses Alsa as Output. The line object Java provides has the possibility to ask for the available bytes in the buffer. Normally with pulseaudio you can see the buffer getting filled and then, as the audio get's played back, recovering by the played back bytes amount. With pipewire-pulse on the other hand it just fills the buffer and reporting no more available bytes. But it plays back the bytes successfully written to the buffer. Meaning its unable to write more, as the available buffer size never recovers, even though the already written ones have been played just fine. I have checked the behavior also on Debain-testing, Manjaro and Fedora. Fedora is the only distro without this problem. Fedora has the package pipewire-alsa in its repositories and installed, which is not available on the other distros. If I have understood it correctly, the alsa functionality should be included into the default pipewire-pulse now, but for some reason fedora decided to keep the extra package? So I'd really like to see pipewire-pulse being the default in the future, but this has to be fixed somehow.
