- Pipewire now requires vulkan 1.3, so we have to disable vulkan
support if this requirement is not fulfilled in order to build
correctly in Leap.

- Update to version 0.3.81:
* Highlights
- jackdbus support is now enabled by default.
- IRQ based scheduling in ALSA was improved and enabled by
default for Pro-Audio profile. It will also link the pcms
together to get lower latency. This now matches what JACK
does and gives equal latency to PipeWire for Pro-Audio
profiles.
- Support both old and new versions of webrtc-audio-processing
to make the transition easier.
- Forced quantum changes by nodes or metadata will now also
force a suspend and resume of the graph, like the rate
changes to make sure all nodes adapt to the new quantum.
This is important for Pro-Audio nodes that need to
reconfigure the hardware to a new period in IRQ-based
scheduling.
- Fix a regression in regex parsing.
- Many bugfixes and improvements.
* PipeWire
- jackdbus is by default enabled now. The idea is that when
jackdbus is installed, the real libjack.so is in the path and
we can become a real JACK client.
- Forces quantum changes by nodes or metadata will now also
force a suspend and resume in the graph, like the rate
changes to make sure all nodes adapt to the new quantum.
This is important for Pro-Audio nodes that need to
