Nvidia stealing audio

I recently tried to connect a Samsung led- tv to a simple Nvidia G210 display adapter, causing my analog sound to dissappear completely.
The fix can be found as decribed here:

First update nvidia drivers to the latest:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update sudo

apt-get install nvidia-current

Then following this instruction found on the mythtv website:

http://www.mythtv.org/wiki/Configuring_Analog_Sound_DVI_to_HDMI#Apply_Modified_EDID

In short, the /etc/X11/xorg.conf needs to be adjusted with a modified EDID which prevents audio to be send through HDMI:

Open your ‘/etc/X11/xorg.conf’ file, and go to the Device section for your video card. Add the line
Option "CustomEDID" "DFP-0:/etc/X11/edid.modified.bin"
to tell the driver to use your custom block rather than acquiring one from your TV. The changes will take effect after a restart of X.
