Sending your laptop sound over HDMI »

Forgive me for being a noob, but I was quite surprised to find out that after connecting my laptop to our TV by HDMI, the TV would display the picture, but not play the sound. Since HDMI carries both the video and audio signal, I expected this to work automatically. I was wrong. The solution is to explicitly set the audio output of the laptop to SPDIF:
...and reset this setting once you disconnect HDMI. With this working, the sound now also plays on our surround set, the Philips HTS8100. The result is superb, especially since I can know use my laptop as a HD player.
While I'm at it, here's another beginner tip for Full HD TV owners. When you try to project your laptop's screen onto your TV and notice that part of the desktop is cut off, don't panic. The problem is that most laptops have a screen ratio of 16:10 instead of the 16:9 that your TV probably uses. The solution differs per TV, but on my TV (Philips Aurea) all I had to do is to set the input type of the port that I use for HDMI to "PC". The TV knows how to do the rest and display the laptop screen as a perfect fit.
