Me:
I'm not aware of anyone these days successfully
using Rosegarden with snd-rtctimer - if anyone out
there is, do say so.
To test:
* start RG (version 1.0 or newer)
* go to Settings -> Configure Rosegarden -> Sequencer -> Synchronisation
* change the sequencer timing source option to RTC
* close configuration window, press play.
It probably doesn't matter whether you have a file
loaded or not.
Success -> play pointer moves smoothly
Failure -> system locks up solid, reboot required.
If it does lock up, you may need to edit your
rosegardenrc to restore the timer setting before
you can run RG again.
