'mount' my sound card

In a prior life, I managed tech support for five years. There are no silly
questions. :-)

   - I've tested the speakers using Windows XP. (I dual boot this
   - Likewise with volume.
   - Double-clicking the volume icon pops two error dialogs:
      1. The volume control did not find any elements and/or devices
      to control. This means either that you don't have the right GStreamer
      plugins installed, or that you don't have a sound card configured.
      2. No volume control GStreamer plugins and/or devices found.
   - esd & produced the same error messages as before, even after a
   reboot and the 'killall' cycle.

Continued TIA

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
