[ubuntu] no sound with nvidia 9650mGT HDMI

view story

http://ubuntuforums.org – Hi, I am having some problems getting sound to work over the HDMI interface on my laptop. I have tried going to System/Preferences/Sound to try and change the settings to HDMI but there are no HDMI options to choose from. How do I find out if HDMI sound is supported by the nvidia drivers I am using? I had a look at this thread; http://ubuntuforums.org/showthread.p...ght=hdmi+sound but am still lost. Video over HDMI works fine, I just have no idea about the sound settings. thanks, Brett. btw I have also had a look at gstreamer-properties but cannot find any options for HDMI sound. (Hardware)
