In my HP Pavilion dv7 the HDMI sound does not work (image works correctly).

I enabled this from the "Audio" panel but sound still comes out from the integrated speakers.

I tried to enable the S/PDIF-1 (I found this in some how-tos on internet) from the ALSAMIXER and also tried o update the alsa drivers, but they appear to be up to date.

I am a simple Linux user, not a guru, and I don't know now what could be the problem. Every suggestion would be appreciated.

You might want to try out PulseAudio Volume Control (or simply pavucontrol).

Open a terminal by pressing Ctrl + Alt + T and type

sudo apt-get install pavucontrol

or install it via Ubuntu Software Center Install via the software center

After installation is finished, open your dash and type pavucontrol. Under 'configuration' tab there should be a list of different hardware profiles. Just select the one you need an close pavucontrol.

That's it.

Thanks for the replt FuzzyQ. I've tried but the result doesn't change: the sound continues to come out from the laptop speakers. – stefano Jan 5 '13 at 16:49
