STR (1) Load Music app (2) Choose any song The content is supposed to auto-play, but instead nothing happens. The progress bar doesn't advance either. Nothing telling in logcat.
This issue seems to be caused by bug 730765. If I revert the patches in that bug then the music player works. I'll back them out on mozilla-incoming and it should resolve this.
Note: to get audio playing, we need |chmod 777 /data/local/tmp|. I'm looking into where that needs to happen.
This works with current inbound and $b2g.
