I am new to linux (hence I'm posting this in absolute beginner talk) and recently installed ubuntu 11.10 alongside windows 7 (which I no longer use). It's all working fine except for one thing. I have no sound through my monitor. I do have sound on windows and if I plug in headphones the sound works fine also. My sound is coming through, alongside my video, a HDMI cable. I don't know if it's any help but my monitor is plug and play (linux wouldn't display at all on my old one which isn't!!!).
Please help!!! I need sound!!!
