Public bug reported:
Sound stopped working on upgrade from 13.4 to 13.10. Up until then,
sound via HDMI worked fine. Now, I get no sound through HDMI. Checked
the Sound Settings and alsa mixer and everything looks fine. If I hook
up speakers to the microphone port I get sound.
I used "ubuntu-bug -s audio" to report this bug (very nice BTW). If
there is any additional information you need or anything you would like
me to try, I am game for it.
