Public bug reported:
I have iMac 15.1 2014. Sometimes my internal speaker works, sometimes
doesn't. When I ran the ubuntu-bug tool, internal speakers worked,
however when I use spotify or youtube from different browsers, there
are no sound at all. I did remove&install alsa-lib again and again but
no luck.
