[Ubuntu Studio 10.04] CPU maxes out

MuseScore 1.1 maxes out CPU constantly on my machine running Ubuntu Studio 10.04 with default settings.

This did not happen with the previous 0.9.x version I used. (Haven't used it in a while so not sure of the value of 'x' - do have files created with that version but don't know how to find what version they were created with.)

Turning off portaudio in the I/O settings resolves the CPU maxing problem, but then ALSA-only playback is choppy, unless JACK is also running.

Temporary workaround is to always run JACK when using MuseScore.

Deselecting both ALSA and JACK in the I/O tab also fixes the problem, even if Portaudio is then running with the ALSA interface (and JACK is not running at all).

Hi Wayne

Are you able to reproduce in a nightly build, or source code for 2.0?
