08438903e5 acp: reset soft volume 
When we have accurate enough hardware volume, set the software volume to
1.0. Also fixes the issue of going to 0 volume and then staying silent
until we raise the volume above 1.0.

d13181fb37 acp: prefer some other profile than Off 
The Off profile is always available but we should only use it as the
ultimate fallback when all other profiles are NO.

9f1d84e37c v4l2: in alloc buffer, don't mmap, just pass the fd 
If we can't use EXPBUF, just put the fd and mapoffset in the buffer
memory. This way we can pass the fd to the client and let it mmap .

a79d1fc866 pulse: tweak buffer attributes some more 
Seems to work well with vlc and firefox other apps now.

d2d722efb3 node: add an ASYNC flag 
The flag means that the process function might not complete
synchronously.

We can use this knowledge to improve the adapter. In sync mode we
can pull before scheduling the converter. In async mode we need to
schedule the follower after the converter to get the data ready for
the next iteration.

We can also improve the stream when it is operating async to schedule
a process call when a new buffer is ready to be filled.

This reduces a cycle latency from alsa and improves latency in
pulse.

584ae678c6 audioadapter: improve the processing loop 
Handle the case where the converter in a source needs more output
buffers (-EPIPE). Schedule the follower in that case and try to
run the converter again until we have output or we can't make progress
anymore.

If the converter needs more data, schedule the follower before we
exit the loop with the data. This gives the follower a chance to get
more data asynchronously for the next iteration.

9dc1c3b168 stream: improve the input process loop 
Only try to reuse a buffer when the io area is not already in
the NEED_DATA state or else we might overwrite a previous buffer
reuse and run out of buffers.
We also always need more input.

PulseAudio (which currently uses a priority of 0), so that it takes
priority while contending for the same device.

1e6615f79d pulse: use the EnumFormat param to set reasonable defaults 
Before the node is started, we don't get a Format parameters and we
don't know the channelmap of the node. This forces us to invent a
channelmap that might be wrong. We can do better by using the
EnumFormat param to extract some defaults for the format, rate and
channelmap. Fixes wrong channels in gnome-control-center when testing
speakers.
