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

Still nothing going on. During this entire time, speaker-test was
running and giving output like this:
$ speaker-test
speaker-test 0.0.8
