Highlights of Pipewire.
- Add BAP broadcast source and sink support.
- Vulkan DMA buf support was merged.
- Fix a leak in the SBC codecs for SCO.
- More bugfixes and improvements.
- 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 results in equal latency
for Pro-Audio profiles.
- A new L permission was added to make it possible to force a link between
nodes even when the nodes can't see each other.
- Libcamera and v4l2 devices now have properties so that duplicates can be
filtered out by the session manager.
- Improve RAOP compatibility.
- ALSA hires timestamps are now disabled by default.
Highlights of Wireplumber.
- A new "DSP policy" module has been added; its purpose is to automatically
load a filter-chain when a certain hardware device is present, so that
audio always goes through this software DSP before reaching the device.
This is mainly to support Apple M1/M2 devices, which require a software
DSP to be always present
- WpImplModule now supports loading module arguments directly from a SPA-JSON
config file; this is mainly to support DSP configuration for Apple M1/M2
and will likely be reworked for 0.5
