[Solved] no sound (ONLY from Musescore) in Ubuntu Precise on chromebook w/crouton
All the other audio software (Exaile, VLC, etc.) was fine, only problem was Musescore, which was very perplexing.
Well, Tuxguitar too, but I believe Ms will handle that with an appropriate soundfont.
I did find the cause of the problem by running it from a terminal command so I could see error messages, namely that it was asking for some things that it didn't have permission for. I then launched it with a sudo from the command line, and it worked, though of course it needed the password entered.
But after that one time... it still works, without the sudo. I'm too much of a linux noob to even begin to have an idea why (it's only about 30 hours since I bought the thing, followed the instructions , and confronted a terminal for the first time) but at least this will be something for fellow "bought a chromebook to have a $200 laptop, but want to use featureful software like Blender, LibreOffice, GIMP, Code::Blocks, etc." types to find when they search the forums before asking their question, or be directed to by the regulars when they don't bother.
If anyone who knows which end of the byte has the teeth wouldn't mind lending their wisdom on this matter, it would be greatly appreciated, but at least I've got a simple fix up for future reference.

IMPORTANT: Per https://help.ubuntu.com/community/RootSudo , don't run it with the sudo command, us gksudo instead, or kdesudo if you're using KDE as your desktop. Plain sudo will make the files you save belong to root, rather than you. I'm not sure if the "run once as root via sudo, then it works" trick does that forever too, but having poked around some more, filled up the chromebook's dinky SSD with useless crap, and deciding to wipe it all via reverting to normal mode and back to Developer Mode, I'm about to discover if the same problem appears in Ubuntu Saucy and if so whether the same trick (but with gksudo) will fix it again if so. I will only post again if the problem appears and the fix does not work, to avoid unnecessarily cluttering up the forum.
