Sound still inaudible.  (I'm using speaker-test as the sound source.  If
this is inadvisable, I'll try anything else you recommend.)  I'll post
the exact commands I typed along with the console feedback to make sure
that everything is done the way it should be done.

$ amixer set 'External Amplifier' off
Simple mixer control 'External Amplifier',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [off]

$ amixer set 'External Amplifier' on
Simple mixer control 'External Amplifier',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]

No sound audible.

$ amixer set 'Master Surround' 80%,on && amixer set 'Spread Front to
Surround and Center/LFE' on
Simple mixer control 'Master Surround',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 25 [81%] [on]
  Front Right: Playback 31 [100%] [on]
Simple mixer control 'Spread Front to Surround and Center/LFE',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]

$ amixer set 'Spread Front to Surround and Center/LFE' off
Simple mixer control 'Spread Front to Surround and Center/LFE',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [off]

Still nothing going on.  During this entire time, speaker-test was
running and giving output like this:
$ speaker-test
