'mount' my sound card

[Gavin McCullagh]

Hi,

silly questions to start off but just in case:

1. Your speakers work, right?
2. The volume isn't just turned down or muted is it?
3. Is there a speaker icon in the top right of the screen?  Can you double
   click and unmute and/or adjust all of the volumes up?

So, esd has started and grabbed the sound card.  Good.  esd would just die
if there was no sound card free.

I'm not clear if these errors are just because esd is already running --
you can't run it twice on the same sound card.  You can kill the existing
esd and try again with:

	killall esd
	ps aux |grep esd        (just to check it stopped)
	esd &

If esd starts properly, you'll usually hear a bleeping sound over the
speakers.
