a2dp-sink writing duplex data to the BT socket breaks a2dp-source source
polling, also in A2DP source role. Hence, use the timer-based polling
workaround always in duplex mode.
As currently implemented, input format convert channel remap is no-op.
This is because although the out_datas array is permuted, the original
pointer array is not referred to later on, so the only effect is that
the temporary data array is stored in permuted order.
Fix the permutation by permuting the pointers only for the conversion
step.
Make a new noise method called PATTERN and use it to add a slow (every
1024 samples) repeating pattern of -1, 0.
Only use this method when we don't already use triangular dither.

When the stream has more channels than the filter inputs or outputs,
don't try to connect an invalid filter port but ignore the input and
clear the output.
pthread_getschedparam() always returns non-negative values, so checking
if its return value is less than zero always evaluates to false.
Also, pthread functions don't set errno. While logging a warning
message, use the return value of pthread_getschedparam() instead of
errno.
First go over all the input and collect pointers and the size that we
need to copy. Then go over all destinations and copy the source or
clear the buffer memory.
This fixes the problem where extra planes in the destination would get
a 0 size, which would make the converter produce 0 output. It also
ensure that the output size is consistent.
Also clamp the amount of input samples we push when flushing. do several
rounds of zero pushing until we have flushed enough.
Handle the cases where no input is needed or no output is generated.
Fixes crashes when downsampling from 96000 to 1000 Hz or so.
The order of attribute changes is random, so it's possible that controlCX is
accessible before the other devices, which marks the device as available but it
actually fails to open. Only consider the device accessible if both control and
PCM devices can be accessed.
This requires reacting to ATTRIB changes of pcm devices as well now.
Fixes#2534
We need to check the last offset against the size of the buffer, not the
remaining size in the buffer.
When the writing is split, this could cause the buffer to be reused
wrongly.
See #2536
