Hi

I am using musescore. I can see the program is building and loading normally. But no sound and playing of scores available. And I cant load any external soundfont. But I can export sound as mp3. So the soundfont is loaded ;-)

The program tells it is musescore-devel. Is this indeed the release version that has been used for the build ??

my USE flags are as follows:
USE="a52 aac alsa archive branding bzip2 cdr dbus dri dts dvd dvdr dvdread exif 
faac ffmpeg flac foomaticdb -gnome gphoto2 graphite gstreamer gtk gui hwaccel 
jack jpeg jpeg2k jumbo-build -kde lame lcms lensfun matroska mp3 mp4 mpeg ogg opengl
pdf postscript -pulseaudio qt5 rar raw sf3 spell theora threads tiff truetype 
usb vaapi vdpau  vorbis webp win32codecs wmf x264 x265 xcomposite xfce xv X zeroconf zip zlib"

Have a nice day

It is sad to read that you have problems with the software. The situation seems to be a bit more complicate and requires some analysis.
We can not help you efficiently via bug tracker. The bug tracker aims rather on specific problems in .ebuilds and less on individual systems. 

I have had very good experience on the gentoo IRC [1] with questions like this. Of course there are also forums and mailing lists [2,3].
I hope you understand, that I will close the bug here therefore and wish you good luck on one of the mentioned channels [4].
Please reopen the ticket in order to provide an indication for an specific error in an ebuild or any gentoo related product.

Hi

Have investigated a bit. When compiled with use=pulseaudio everything works as expected with pulseaudio as frontend. But still no alsa. The bug is most probably in qt. There is a fairly recent report of pure alsa not working (qt-alsa works when you change permissions for qt-pulseaudio so it cant be loaded). This is maybe also one reason why debian has not updates to a more recent version, but stays with musescore-3.2.3.

But it will be quite a work to let musescore compile without qt ;-) And I have decided to try setting up my audio workstation with pulseaudio as useflag. Lest see how it goes (so far OK).

Have an ice day
