Make the channels configurable for capture, source, playback and
sink streams. The playback and sink stream need to have the same number
of channels but the layout can be different.
Use init2 of the echo-cancel plugin when available to pass this info
around. The echo-canceler will then further adjust the settings to make
things work.
The raw biquad takes its values from the config and then updates the
control ports with them in activate. At runtime, the changes to the
ports are applied to the biquad.
Other biquads take values from the config ports in activate.
When the timing_port is 0, just don't send out an initial timing packet.
When we receive a timing packet, reply to the same address/port that the
timing packet was sent from.
Fixes#3133
We need to be able to fill up one quantum of data when the stream
requests it so suggest a quantum_limit buffer size. Normally, the
converter will further improve the buffer size parameters when
resampling is involved but this is a good default for when working in
passthrough mode.
We don't actually use the stream buffering features so we're happy with
just 1 or 2 buffers.
Make an option to allow link.passive properties and set it to false by
default.
This effectively ignores the link.passive properties from the session
manager, jack clients and pw-link when set. This is a good idea because
the logic for making passive links is better handled in the core.
We are not allowed to call pipewire methods from any other thread than
the main thread so use invoke to schedule a module unload from the
pulseaudio thread.
Fixes some infinite loops when the work-queue list gets corrupted.
Filling a buffer with zeros to produce silence is wrong for
unsigned sample formats and compressed sample formats. This is
silence with an offset. A silent stream with unsigned or
compressed samples mixed with another stream produces a clipped
stream. To hear the problem start QEMU with
qemu-system-x86_64 -accel kvm -smp 4 -m 4096 \
-audiodev pa,id=audio0,out.mixing-engine=off \
-machine pc,pcspk-audiodev=audio0 \
-device ich9-intel-hda -device hda-duplex,audiodev=audio0 \
-boot d -cdrom Fedora-Workstation-Live-x86_64-37-1.7.iso
on a host configured to use PipeWire and start audio playback on
the guest HDA device.
PA_SAMPLE_U8 is the only unsigned PulseAudio sample format.
There is no need to care about unsigned multi-byte formats.

Emit both the bound_id and bound_props events from the protocol on
the core_resource.
Doing the dispatching of the bound_id/bound_props in the core to the
proxy doesn't handle the case where the client has a listener directly
on the core_resource.
Fixes#3109
this event extends the bound_id event and sends the global properties as
well.
This can be used to get the object.serial, for example.
It can also be used in the future to let the server generate unique
property values, like the node.name, and let the client know about the
new property value.
Fix Digest, we need to use the method to generate a new Digest for each
request.
Use newer openssl methods instead of deprecated ones. The RSA sign still
need to be ported.
