HDMI for sound not working

[famebu]

I have my monitor and tv setup with twin view and am trying to use the hdmi to get sound though my tv but nothing I do seems to work.
The master channel is set to hdmi but still doesn't work it will still only use my speakers. I have tried setting every other thing is the sound options to hdmi and it still doesn't work.
The only way I am able to get sound via hdmi is to use vlc and select hdmi as audio device and it works just fine then but i am trying to watch a movie on youtube and can't do that.

I have never setup dual monitors before so I am probably just missing something, thank you for the help!

I had similar symptoms on a recent HTPC build (HDMI sound via vlc but not flashplayer) - eventually solved by setting a default pulseaudio device via /etc/asound.conf (you can also try it in ~/.asound.rc I think)

pcm.!default {
    type hw
    card 0
    device 3
}

where the card and device #s are your HDMI outputs (from aplay - L, or look at the working config under vlc -> Tools -> Preferences -> Audio)

Just something to try

Hello,

similar problem with
HP pavilion g6 under Ubuntu 12.04-64bit
Laptop connected via HDMI cable to TV.
Video output OK but no sound using vlc as media player.
What exactly would I have to do when you say

solved by setting a default pulseaudio device via /etc/asound.conf (you can also try it in ~/.asound.rc I think)

I would appreciate if you could give me more detailed info as I'm not a software expert?
I have attached the terminal output of command

aplay -L

OR
terminal output for cat /proc/asound/cards
