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] > Next, try: amixer set 'Master Surround' 80%,on && amixer set 'Spread Front to > Surround and Center/LFE' on > If sound is still inaudible, revert the change to 'Spread Front to Surround > and Center/LFE' only.
