MuseScore 3, Windows 10.0.18363 Build 18363

I have had this problem ever since installing MuseScore on my computer a few days ago.

I've tried:
Factory Reset
Updating Sound Drivers
Restarting Audio and MIDI Devices
Unticking 'Exclusive Access'
I cannot find MuseScore in my volume mixer


What version of MuseScore 3? (MuseScore three point what)
Have you tried to re-boot your computer?

In Windows 10 Control Panel -> Programs -> Uninstall a program select MuseScore 3 and use the 'Repair' option.

We'd love to address it, but so far no one has been able to come up with precise steps to reproduce the problem. It either happens or it doesn't, it seems, and so far its never happened on any system any of us developers have seen, so we can't really debug it. If someone manages to figure out how to reproduce it - to find the series of commands we need to execute, drivers we need to install, or whatever - then we can begin to investigate further. So we're kind of dependent on those users who have experienced this prolbem to help out in the detective work by doing more experimentation on their own systems - updating drivers, changing audio settings, uninstalling other programs, etc.

I have the same problem: no sound. But Find out, that in the mixer there are for each sounds 2 possibilities, for example "Flute" and "Flute expr.". All the sounds with the "expr." doesn't work. Unfortunately muse score choose by default the wrong sounds if you do that directly in the score. If you choose "flute", muse score choose in reality "flute expr.", but you see that only in the mixer view. If you don't change the instruments in the mixer, you won't hear nothing.

To be clear: the expr sounds do work by default. But if you've installed some soundfont other than the default, we can't guarantee it supports the same sounds we do. My guess is that is what is happening. So you might need to try other soundfonts, or try different settings the Dynamics tab of the Synthesizer window that are a better fit for your soundfont.

By default, if you add a flute, it just works.

In any case, though, this is kind of a different issue if you are experiencing soundfont / dynamic incompatibilities, your play button wouldn't be disabled. That indicates an incompatibility or conflict with an audio driver somehow, and that is what we still haven't identified.
