yes, kind of strange, i see your point.
nevertheless this was the observed behaviour with ardour playing back a
project of 16 stereo tracks. the ardour gui was very jerky and slow to
update. reducing the rt priority of soundcard improved UI response,
BUT i must admit that i was not very systematic in my efforts to improve
latency on my box, often twiddling several knobs at once.
regards, G.
you can set the rt priority as high as 99, but i
found that this
made my box sluggish and unresponsive ( but not the soundcard!).
Isn't that kind of strange ? Assuming the soundcard interrupt
takes a tiny fraction of the available CPU time, it shouldn't
slow down your system even at the highest priority.
If this happens, and it does not happen with your current
(lower) setting, wouldn't that mean that
1. it takes a more than trivial time to execute,
2. with the current setting it's still being
pre-empted, and not just occasianally, but
in a systematic way.
