i'm very new to ubuntu/linux. I installed Ubuntu 12.04 LTS on my vista laptop (nvidia gpu) in dual boot and with some help of google i'm almost ready to go. The only thing that i can't figure out is how to play sound trough my hdmi connected to my tv. Speakers of the laptop are ok, in te sound settings i can see -hdmi -digital -speaker outputs. The top 2 won't play sound so i googled around, found a bunch of things to try but the only thing succesfull so far was to erase all the drivers from the audio settings and they stayed gone. So finally i re-installed from scratch but still no sound trough hdmi. Re-installed 6times in the last 3 days now so the only thing left for me is reaching out for help/advice about this. How can i play sound on my tv connected with hdmi? I will be glad to give more info if needed cuz this is driving me crazy, thanks for your help in advance !
