I have ubuntu installed on a Acer aspire revo 3700 intel atom processor with nvidia ion graphics this is plugged into a celcus 32 inch TV via HDMI (1080p). The video driver shows as an nvidia which I can select. I have set the sound to play via HDMI and the output to HDMI but get no sound. I have tried a sony 1080i TV with the box but get eratic results with the graphics, but the sound picks up straight away that is there is no need to select it.

The graphics on the celcus TV work but I get a dialog box showing loads of different resolutions and frequencies which I have to close manually, these appear to be attempts to set different resolutions for the TV.

Am I missing some sort of screen/sound driver, if so does anyone know what might support the celcus 32 inch (1080p) tv?

You do not need tv-specific drivers like drivers for monitor. You need driver for video card. apt-get install nvidia-current-updates

Already downloaded the latest updates, why would sound work on one tv and not another with the same drivers? –  Goony Hill Feb 26 '12 at 23:40

You should make sure you sound on your computer is muted, while the HDMI Output is un-muted. Just open up the sound settings, mute internal sound, and make sure HDMI is set to output (and not muted).
