Ubuntu refuses to output audio via HDMI

My issue is that I can't get sound to my TV which I connected via HDMI cable to my HP Pavilion g6 Laptop running under OS Ubuntu 12.04-64bit.

Terminal output about audio hardware:

List of PLAYBACK Hardware Devices:

jg-laptop@JG-Laptop:~$ aplay -l
card 0: Generic [HD-Audio Generic], 
device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], 
device 0: STAC92xx Analog [STAC92xx Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0


jg-laptop@JG-Laptop:~$ cat /proc/asound/cards 
0 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xf0544000 irq 44     
1 [Generic_1 ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xf0540000 irq 16

I have no choice in System Settings -> Sound to select HDMI audio output

No HDMI audio

Please can somebody tell me what is missing and what I would have to do?

you should update your graphics card . – user84277 Oct 16 '12 at 20:29

You can try installing program "PulseAudio Volume Control" (sudo apt-get install pavucontrol) and in tab "Configuration" select profile mentioning HDMI.
