Sounds Great

Just thumbed through the MagPi, all good stuff.  Issue 3's got a nice page on finishing off the set up (page 4), especially mentions sound.   I'm not going to regurgitate the incantations verbatim, you can all go and read it from source.  Instead, below is a cut and paste recipe. What I forgot to mention yesterday, before signing off for the night, was that I did run the all important:

sudo apt-get update

And this proceeded with out error - wifi etc still intact this PM.

Sound
Will report that it took about 2 min and worked fine

sudo apt-get install alsa-utils
sudo modprobe snd_bcm2835
sudo amixer cset numid=3 2 # Setting up for HDMI out

sudo nano /etc/modules # enter snd_bcm2835 on bottom line ctrl-x Y

sudo reboot
