I’m connecting the computer to the tv with hdmi quite often. Every time I have to change the audio output device manually by going into sound settings inn windows 7.
This is kinda tedious to do, so today I looked for a program to do the switching for me.
Found this; Win7AudioSwitcher
Great little tray program!
Best thing is that it seems to remember which audio output and main mointor I use together. It then changes to the correct audio output device when I change the main monitour, automatically! 
Have made a .hid file (Sony Ericsson Remote Settings File) that I send to my phone to make it an excellent bluetooth remote for XBMC.
Download url:XBMC.hid
Also included are volume control on the “side-buttons”
Update:
Wanted to have a shortcut to favorites on the remote.
Added the following to the file xbmc-folder\system\keymaps\keyboard.xml:
<h>ActivateWindow(Favourites)x</h>
Then updated the .hid remote file to this: XBMC.hid
.xcf gimp file for image: xbmc-remote.xcf
Just needed to extract the audio from a movie under linux,
and thought it would be a nice thing to share.
The software i used is called ffmpeg, and should be easy to install (or allready installed) in most linux distrobutions.
I simply ran the following command, to extract the audio from a movie:
ffmpeg -i input.mov -vn -acodec pcm_s16le -ar 44100 -ac 2 output.wav
ffmpeg -i mandelbrot.flv -vn -acodec pcm_s16le -ar 44100 -ac 2 mandelbrot.wav
