If the follower of the adapter emits an error event, the adapter needs
to forward it to upper levels so that they know the node has errored,
and handle the situation.
Improve the debug_params output.
Always either print the failed filter or that there was no filter.
Print the index of the enumerated failed param or a message when
there are no params.
See #2383
After emiting the node info, remove the properties from the info again
so that we don't accidentally emit them again later, when the
info and properties are out of scope.
Try 8 times to make progress, if nothing after that, xrun.
A stream that keeps sending 0 sized buffers would otherwise get into
an endless loop.
See #2359
Increase the FC filter frequency to 12KHz for better dialogs. This
filter is only applied when making the FC from FRONT channels so that
we keep the high frequency signal on the FRONT mostly.
Increase LFE filter frequency to make slightly more bass.
Disable widen filter by default.
Update config files with the correct defaults.
We can't have a default that simply copies channels, that's just
wrong. So we enable PSD again.
PSD does a good job of moving the ambient sound to the back. It's
subtle and almost stereo like but it's better than plain stereo.
The stereo widen has been reduced to make it more like the simple
upmixing.
People that previously wanted the copy-channels-experience had to
manually enable this in pulseaudio so it's not too much to ask
to manually switch the algoritm to simple. I think this is a better
default.

The PropInfo either has a registered id (and then also a name from the
type-info) or a custom name as a string.
In all cases, the description contains a free form text that clarifies
the property.
Use the description in the stream controls name.
And use this in spa_json_format_float() where we also avoid invalid
json floats.
Use json float format in some places where we serialize json floats.
Add a unit test.
See #2223
Add a property to select the upmix method. PSD is enabled by default
but a new simple upmixing algorithm is available that duplicates
channels and avoids lowpass filter on the FC and disables widening.
Fixes#861
We alwats want to adapt to the rate of the graph and not the
samplerate that was configured with the PortConfig.
This fixes samplerate switching again.
Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.
