Won't play after computer has slept

• Mar 29, 2021 - 22:06

I played a score several times, then let the computer sleep. When the computer woke, the score won't play. When I click the start/stop play button, the bottom status bar on the screen switches from "normal mode" to "play" but the score doesn't play.

If I restart MS, then it plays fine.

MS version 3.6.2, downloaded 2 days ago. Windows 10, brand new 2 days ago.

There are programs that don't work after being put to sleep. Don't know if MuseScore is one of them.

Oh, OK, that's good to know. Thanks for the tip.

Yes, there have been reports about MuseScore being affected by this too.

Possible cure: toggle (off and back on) the MIDI button (in the toolbar, looks like a 5-poin DIN connector)

Any chance you have an external monitor with speakers connected?

I have bluetooth headphones connected. But in normal play, the vertical bar moves through the score as play happens, but in my case there is no such movement.

So I don't think this is a problem with MuseScore. It's more of a workflow thing. It might be system specific, but I don't think so.

An external audio device thus.

One of the issues here seems to be that your operating system (such as Windows) renumerates all audio devices when it wakes up from sleep mode; but doesn't do so transparently. This means that programs such as MuseScore aren't notified that the pointer they have to the pre-sleep-audio device is no longer available.

Try pressing the MIDI-button twice after wakeup to have MuseScore refresh its list of audio devices (or go into Edit > Preferences and press the Restart button there).

I see. Than would make sense. Thanks for the tip.

Actually, that didn't work. Even reboot didn't help - the PLAY arrow was still greyed out.
What did work was to disconnect my Bluetooth headphones, then restart MuseScore.
So, not a MuseScore problem, but Windows/Bluetooth. Hope this helps others.

Then you had a different issue altogether, as this was not about the play arrow being greyed out, but about when waking from sleep the play cursor not advancing after pressing play.

So I have experimented with this.

Get MuseScore playing using BT headphones.
Put computer to sleep by closing laptop.
Open laptop and wake up computer.
MuseScore looks normal. Nothing grayed out.
Hit playback arrow. No playback or progress bar.
Hit restart in Preferences, I/O. No playback or progress bar. Nothing grayed out. This is not a surprise
because the Apply button did not activate.
It can be tricky to decide how may buttons to push because at some point, MuseScore goes into the No
Response blue spinning wheel of death mode, from which it never recovers.
Push the toggle midi button 3 times (why 3. No reason). Normal playback resumes.

Personally, while I have BT headphones and mouse, I don't really use them much because of these kinds of connection problems in general. But, that's just me.

Next time drop steps 6 and 7 (the restart button works on it's own, does not require the apply button at all) and in step 8 only press the midi button 2 times.
