No Audio Output from MuseScore

• Apr 26, 2014 - 17:26

Hi,

I have tried using MuseScore 1.3 in Ubuntu Studio 14.04 x64. I can get audio out of other apps just fine, but cannot from MuseScore. when I run it from the terminal I get these messages:-

PulseAudio found, but no need to suspend. Starting mscore.real...

Is this anything to do with it? I've tried just about every combination in the I/O tab of Preferences.

Does anybody have any ideas? I'm really stuck. Tried several solutions I've found on the web, but to no avail.

Thanks in advance,

Hi,

I think I've solved my own problem, but I'll post the solution in case anyone else has the same problem.

When I tried using MuseScore, I had JACK and QSynth open and they were using the connection to my soundcard. If I reboot, don't start QJACKCtl or QSynth, In MuseScore Preferences I/O pane, my sound card now shows up, and I can use it as my output. The only problem being I can't use MuseScore and QJACKCtl & QSynth at the same time, but that isn't a major problem, just wish I didn't have to reboot every time, even logging out won't work. If I've had QJackCtl and QSynth running, even if I close them, the sound card is still not available for MuseScore.

Hope this is of help,

This is how i fixed it. Edit tab then go to I/O tab than to the Portaudio portion of I/o.
have api set to pulseaudio and set device to pulse. That seemed to solve my problem atleast for now until a fix is found.
