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.
