That one seems to have went off without a hitch

> amixer set PCM unmute

amixer set PCM unmute
amixer: Unable to find simple control 'PCM',0

Then went to root and tried again:

 sudo amixer set PCM unmute
No protocol specified
xcb_connection_has_error() returned true
Simple mixer control 'PCM',0
  Capabilities: pvolume pswitch pswitch-joined penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 0 [0%] [-34.50dB] [on]
  Front Right: Playback 0 [0%] [-34.50dB] [on]

It appears the left and right are `on' but yet I cannot hear any
sounds. At least I am not able to make a sound with something like:


   mplayer /anex2/music/W.P.A._CaseyBillWelden.wav

And the numbers spin by but no sound.  Yes, I do have speakers
connected... hehe.

And I hear noise at the speakers when I pull the plug in and out.
