Public bug reported:

I bought HDMI cable to connect my Ubuntu PC to TV. Everything works well
but when I start playing music on PC there is no sound on TV. I changed
output in sound settings to HDMI but it doesn't work. Playing music
through computer speakers while PC is connected to TV works fine.
