OK, Selecting 1 or 2 in zypper did nothing same as 3 and 4 did. I got it to install by zypper rm alsa* zypper in musescore It hung the machine - then I realized that I needed to reboot to remove the alsa code After reboot musescore loaded but does not play midi other than a note or 2 a second. Not sure new bug on zypper and musescore not playing correctly? Do I reinstall alsa and uninstall pulseaudio and try again?
