Based on the measurements I have the impression
that more is going on in the
USB audio driver than just 1ms packages.
I'd agree.
When I use alsa_delay with 96/2 things are OK for around 10
seconds, then for another 10 s I get all sorts of weird values,
and finally a stable value that is a few tens of samples higher
than the original. This stable value is different each time
the test is run.
For 48/2, I get unstable values for the first 10 seconds, then
a stable value that is again different each time.
It almost looks as if something tries to adapt to the situation,
but not in a deterministic way.
