Mumble doesn't work in PulseAudio mode.

Version, Distribution, Desktop Environment: Latest master, Arch, xfce4

Description of Problem: No sound in Mumble in PulseAudio mode.

How Reproducible: Use mumble (config wizard is enough I think) and set PulseAudio mode (default I believe).

Actual Results: No sound from connected headphones; no stream appears in pavucontrol; stderr of Mumble shows i/o error.

ALSA mode works but it's probably bugged af in Mumble itself.
