The following might be a problem in your alsamixer settings:

# Simple mixer control 'Master Mono',0
# Capabilities: pvolume pvolume-joined pswitch pswitch-joined
# Playback channels: Mono
# Limits: Playback 0 - 31
# Mono: Playback 0 [0%] [-46.50dB] [off]

So first unmute the Master Mono channel in alsamixer or gnome-alsamixer and increase the volume to 77%

Then try this:

Double click on the volume control, click on Edit/Preferences, then check External amplifier to be visible. The switches tab then appears. Uncheck 'External amplifier' in that tab.

Hope this helps.
