Bug Description
CID: 201307-14037 Dell Vostro 5470
There is no HDMI audio output option available when you connect the HDMI monitor (with speaker) to this system.
Verified with cold plug, still no luck.
However, HDMI audio could be detected with cold plug on 12.04.4 (3.11 kernel) stock Ubuntu, tested with LiveUSB
