Hello, sorry my bad English. Almost every launch freezes, consumes 100% CPU and clogs up .xsession-errors. I am attaching the information. Deleting configs does not help. Reproducible: Always Steps to Reproduce: 1.Just start 2.Maybe you need to upload a score 3. Actual Results: freezes, consumes 100% CPU and clogs up .xsession-errors

There is sound in the system, qmmp is playing.

# emerge -pv media-sound/musescore These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] media-sound/musescore-3.6.2::gentoo USE="alsa mp3 sf3 -debug -jack -omr -osc -portaudio -portmidi -pulseaudio -sfz -webengine" 0 KiB
This is just a guess based on experience but the "Broken pipe" coming from ALSA is likely indicative of either CPU not being able to keep up due to excessively tight latency requirements or perhaps interrupts interfering with audio thread scheduling (but to a degree that's still CPU not having enough cycles to deal with it). Or it could be a bug somewhere. What are the settings of the MuseScore ALSA driver? On my system 48000 Hz sample rate with 3 fragments of 256 samples per period works fine (running on pipewire with ALSA applications being routed to pipewire-pulse by the PulseAudio's ALSA plugin).
Could it be that I moved an extraneous sound bank (.sf2) to a different location, but the old place remains in the scores?
Removed all configs and scores, completely all traces of life. Rebuilt musescore with some dependencies (mostly dev-qt/*). I launched it (load on one processor core is 100%) and started composing the score from scratch. After typing 8 clock cycles, it hung (the contents of the window are not visible on the screen, only the title, the load on one processor core is 100%). "killall musescore" solved the problem, the score was gone))
you might want to compile musescore in debug mode and then run it using gdb. once musescore gets stucked, you can press ctrl+c in gdb and inspect the threads. here are some hints: * https://wiki.gentoo.org/wiki/Debugging_with_GDB * https://stackoverflow.com/questions/24810662/use-gdb-to-find-where-program-stuck
Can strace be used? gdb is too difficult for me))
(In reply to globus from comment #9) > Can strace be used? gdb is too difficult for me)) i guess you can use strace too.
Created attachment 715764 [details] strace out I didn’t type the score, otherwise the log would be too big.

Just want to CONFIRM: I've never had this problem until today. I didn't just emerge MuseScore; it's been working fine until now.

The only thing that stands out immediately is JACK2: Sun Aug 22 13:36:28 2021 >>> media-sound/jack2-1.9.19 Which backend are you using for MuseScore? I'm not familiar with them but in my testing, IIRC, even if I disabled everything else, MuseScore would still not automatically pick JACK making me suspect it might be buggy or have some other issue that makes it be strictly opt-in. And a follow up if you're using the ALSA backend - is that native ALSA or are you then routing the audio to JACK or another daemon? Finally please check out comment 8 by Miroslav on how to try debugging the issue itself.
I've been using the ALSA backend for a least a year, maybe for years. I uninstalled and masked media-sound/pulseaudio. The use flag is also "-pulseaudio" for everything. Please have a look at this--seems to be the same thing--issue as discussed by MuseScore developers: https://musescore.org/en/node/314891 SEE ALSO: https://github.com/alsa-project/alsa-lib/issues/107 I will try the 1.2.5.1 media-libs/alsa-lib

Upgrading (unmasking and emerging) to =media-libs/alsa-lib-1.2.5.1 did the trick for me. I've got sound again in MuseScore!
