The channelmatrix was limited to the 19 known channels, leaving
only the first 19 channels usable.
Use the full 64x64 matrix instead and make sure to fill all 64
channels with the identity matrix in the case we need to copy or
distribute the matrix to unknown positions.
See #57
Just leave them be. Something else is supposed to changed the volumes
if needed. In the usual case where nothing changes, we don't want to
override the volumes.
Remove the soft mute/volume events, add a new method to get the soft
volume and use the volume_changed event to emit the changed soft and
monitor (real) volumes event for the node.
Make sure the monitor ports always uses the monitor volume, which is the
real volume unaffected by the mixer volumes.
This configures the soft and real volume on the sink/source in all
cases and makes the monitor port follow the real volume of the sink.
See #897
Make info parsing a bit easier to read by assigning the key and
value to temporary variables.
Improve the parsing of channelmap using json parser to make it
support more cases.
Add a unit test for channelmap parsing options.
Avoid calling memset on a large piece of memory when draining
the resampler because it might use up all the allocated time in
our realtime thread. Instead use a prealloced empty buffer.
Keep all the children param flags around and use those to decide
if something changed. Also don't change the param flag serial when
we are simply adding a listener.
This should reduce the number of param updates, most notably the
PropInfo that was updated along with the Props on volume changes.
Take the queued input samples into account when calculating the
required input size. This can be 0 when there is still enough
data queued in the input for another period.
Handle 0 read_size in alsa-source and make it push out a 0 buffer,
this will then drain the resampler and make it ask for a new buffer
size. This makes the transition from one period to another more
seamless for the resampler.
Fixes#805
Keep track of the param changes with the user counter. Make sure to
flip the serial switch whenever a change is pending. Previously
we copied the param from the channelmixer or follower but that
did not always result in a serial change.
Fixes#764
Keep track of the subelement we're iterating in the result index upper
bits. Use enum_sync to iterate each param and switch to the next
element when we run out of params.

Implement monitor volumes in the merger. There are two volumes,
the channel volume and the monitor volume. The monitor volume
is always applied.
By default the monitor volume will now follow the main volume of
the node. This can be disabled with a monitor.channel-volumes
property.
