Bug#748545: Does not work - starts, but does nothing

[hermann meyer]

Hi

gxtuner works here without problems.

Do you use jack with rt-priory ?
the pitch-tracker thread in gxtuner runs usually with jack-priory -6, so 
a lower priory then jack itself and all other jack-aware apps. This is 
done to never conflict with other audio threads which may work on 
critical (real-time) data.
If you use jack with a to low rt-priory, or without rt-rights, it may be 
that the pitch-tracker thread never get finished before the time-line ends.

greets
hermann
