A sound issue on macbook2015

• Dec 12, 2015 - 23:05

Hello. There is a sound issue on my new macbook 2015. Whenever I try to play my score on Musescore, the sound from a built-in speaker has cracking noise which is really annoying. But the sound from other application, such as iTunes, and safari, so far works quite well. Do you think this is a hardware issue?Does anyone have a same(or similar) problem?

I have this too, and tried it with 2 different 12" MacBooks.

I tried different sound fonts, and get the same thing.

Sibelius works and plays back without the crackling, so I'm thinking it's not the hardware.

Well, the soundfonts themselves don't clip noticeably; any clipping would you are hearing be introduced during playback by the fluidsynth engine if the volume is set to high. Your sound level looks to be near the default, which could potentially clip in extremely loud passages. Again, have you tried turning it down further? Say, down to the "30" line? If you still hear clipping how about if your export to MP3 and play that in iTunes? If you hear clipping in the exported audio, maybe you could post that so we can hear what you are hearing?

The crackling noise even appears on Garageband while Musescore application is running in the back.(Does not happen when Musescore is not running.) When i tried to play a midi file that i created on Musescore on Garageband, the crackling noise also appeared. I thought at first that there is something wrong with my macbook, but the noise disappeared when I quit Musescore application that has been running while the midi file is played on Garageband. So I think this is more of a technical issue, not equalization or voluming.

You mention that when you close MuseScore the crackling noise on Garageband stops, yes?
So, have you absolutely, positively tried the factory reset?

If you have definitely done the factory restore, try this:
Replace the -F (for factory reset) with the -s command line option and see if Garageband still crackles. The -s command will load MuseScore with its internal synthesizer disabled - to see if that's the problem. Then see whether Garageband still crackles with MuseScore running (without its synthesizer).

For info. on command line options, see:

I'm using Windows 8 and did make install.
I've recorded what's happening. You can see the movie if you click "Click here" below. It crackles so much, but when I set the synthesizer to "No Effect" rather than the default "Zita1", the noise gets reduced significantly (but still there). If I set it back to "Zita1", it crackles again.
- How does the synthesizer setting affects the crackling?
- I don't have the same issue with my 2.0.3 prebuilt binary. Anything wrong in my compilation?

Thanks a lot for your help in advance.
