Here's a bit more detail for discussion before I send this over to the PA
guys for feedback.
I am seeing the time period returned by jack_delay regularly increase
during the measurement process. Do you have any thoughts on why that would
be happening? I would like to rule out jack_delay because this is most
likely a bug in PA that I have come across now.
I'm using this method:
jack is now set to 64/48000/2
This is the graph:
jack_delay -> pa_source -> audacity -> pa_sink -> jack_delay
Using audacity with 0 internal latency and in pass through mode I see the
following results. It starts out as 10.667ms and after a few seconds it
climbs up to 70.667 ms.
I see similar results with ecasound instead of audacity using the
following graph and ecachain:
jack_delay -> pa_source -> ecasound -> pa_sink -> jack_delay
ecasound -f:32,2,48000 -b:64 -i alsa -o alsa
In that case it starts at 60.000 ms and climbs upto 572.000 ms after a few
seconds of running the test.
