Hi,
I can't see what's wrong with the calculations I'm performing for
timebase/transport in my JACK app. I'm not sure where the error lies.
I keep looking and looking at it, changing bits, experimenting, and
still not getting the desired result.
Everything is playing too slow. For example, @
Hi :)
today I compared a default Ubuntu Studio with and without the
proprietary NVIDIA driver. Note that for Ubuntu Studio 2 tests failed
because of time out errors, but even the tests that were passed with
success are significantly less good, than the tests with openSUSE, were

Hi Ralf,
You are comparing a banana and an orange to find out which one is
sweeter. Given the nature of the problem it would help a lot to have as
little differences between the systems under test, otherwise it's
impossible to track it down.
I hazard a guess that it's Ubuntu's 2.6.32

OK, so the proprietary driver seems to yield better 'worst latency' values
compared to nouveau. That's kind of odd, anything X-related would

I am using KX Studio. Latest Mono version is 2.4.4 from SVN, though the latest
version is 2.6.4. Latest monobristol version from repository, 0.40.5, works,
but bristol version there is 0.60.1.
I compiled latest monobristol (0.60.1) with defaults and installed to
/usr/local. It worked when
