Use codec methods. Init codec at start.
Remove rate match until we actually implement this
Add some buffering of packets before we hand them out.
Always simply fill a buffer and hand it out.
don't emit signals when we are following another driver.
Acquire transport as soon as it goes to PENDING.
Make the list of supported codecs available.
Register all supported codecs endpoints
Find the codec from the endpoint name
Put the codec on the transport for the sink to find.
When we receive volume updates with a different number of channels
than we are configured for, remap them to our number of channels.
This currently involves taking the average volume until we actually
have a channelmap associated with the volume updates.
See #320
When a port is plugged/unplugged, first update all the profile states
and then emit a profile change only for the current profile. This way
the device can look at all the updated profiles to select the best one.
Some drivers seem to only use 2 buffers when asked for 16 buffers. We
can see this because the buffer is already queued. In this case, just
use the 2 buffers.
See #294
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.
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.
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.
