Title:
rosegarden 16.06 plays only first note, locks up PC when trying to use
HR timer
Status in linux package in Ubuntu:
Confirmed
Status in rosegarden package in Ubuntu:
Confirmed
Bug description:
I don't know why, but I cannot remember Rosegarden ever to be working
during the last ten years.
I load up some of the examples shipped with it, try to play it, the
playback counter starts to wildly fluctuate back and forth around the
time point 0. When I try to set the HP timer as timer source for the
sequencer, the entire PC freezes. I tried this with regular linux-
generic kernel on amd64, and low-latency stock kernels from Ubuntu
16.10. The only way to get the timer on the playback display going
forward is to select a recording or playback device as a timer source.
But even then only the first note gets played and nothing more. I even
tried not having any devices connected to rosegarden, but the playback
timer just kept fluctuating around 0.
