Ok, I went back and recompiled some things to find out just what does and doesn't work. Turns out that if only I'd removed the modules from the /ubuntu/sound directory the solution from http://ubuntuforums.org/showthread.php?t=556217 would have worked just fine.
Looking over the patch_via.c files it appears that the one from via- linux-audiopackV1.5.tar.gz and the one from the forum thread do pretty much the same thing, the most important part being setting some bit to 0x20 (though I know nothing about c nor sound drivers, and spent a whole 30 seconds examining this, so don't overvalue my opinion) -- Headphone jack does not work in NC1502 https://bugs.launchpad.net/bugs/184314 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
