PipeWire 0.3.73 (2023-07-06)

This is a bugfix release that is API and ABI compatible with previous
0.3.x releases.

Highlights

Fixes an ALSA resume after suspend error.
Handle and disable seemingly wrong hires timestamps from ALSA.
Filter-chain now has loadable plugin modules. The LV2 and sofa plugins are
moved to a separate .so file to make things more modular.
Rate changes in the graph should now be handled more gracefully by loopback
and filter-chain.
A regression in the rtp-sap module was fixed where it would in some cases
fail to start.
A potential crash in the peaks resampler was fixed.
Many cleanups and other small bug fixes.

Fix a potential segfault when no fallback driver was set in the config.
Improve OPUS detection.
Add ASYNC flag to pw-filter and pw-stream when queue/dequeue is not called
from the process function. This ensure we allocate an extra buffer.
Discard pending process callbacks when disconnecting. (#3314)
Cleanups and improvements to the debug environment variable parsing.
The graph rate was tweaked to better handle very low rates such as those
requested by pavucontrol when it does the signal monitoring.

An example filter module was added.
Filter-chain and loopback now disable the resamplers if no rate is specified
and will always follow the graph rate.
Improve setup of filter-chain. The graph is now created when starting
because this ensure the target graph rate is known.
Filter-chain can now link notify ports to control ports in the graph.
Filter-chain now has loadable plugin modules. The LV2 and sofa plugins are
moved to a separate .so file.
A regression in the rtp-sap module was fixed where it would in some cases
fail to start.
Module-rt now has options to disable rlimits, portal and rtkit.
module-raop-discover now has an options to set the latency. (#3247)

Disable rate negotiation when the resampler is disabled. We will always
follow the graph rate.
Set device.icon property for UCM ports as well.
Improve ALSA recover when using hires timestamps. This fixes some problems
after resume from suspend. (#3315)
ALSA will now warn and disable hires timestamp when they seem wrong.
They can also be disabled manually with a property.
V4l2 will now gracefully handle ENOTTY when enumerating frame sizes and
frame rates. (#3325)
A potential crash in the peaks resampler was fixed. (#3320)

A client crash in pavucontrol is avoided by always setting a card name.
The graph rate is now taken correctly when using the FIX flags. (#3317)
An option was added to ignore the FIX flags of a stream. Also the
documentation for those options was updated. (#3317)
module-raop-discover now support latency_msec. (#3247)

Remove an assert and issue a warning/recover instead when a buffer is too
small.
