PulseAudio support is not yet fully implemented
I tried using PW as sole sound management system with replacement of PA and JACK. Haven't tested JACK compliance yet but immediately noticed that there are quite a few missing functions (can't list them now because of tests on a different system) in PA support, so paman
dies and pavucontrol
complains. Meaning that, depending on what applications expect, they may be partially or fully inoperable yet.
#249 (closed) may be considered a subset of this issue.
