Yes, I think you might be -- the output below shows that
amixer _has_ responded to your command. Look at the
bottom 2 lines of each response -- for example
Headphone said "Front Left: Playback 50 [79%] [on]"
indicating that it has responded to your command by
setting volume to 50 and switching sound ON (un-muting
it, in other words).
Try amixer set Headphone 10 mute
and compare the two outputs line by line to see the
difference. Then put it back as you have it below as
that's more sensible!
OK the settings are being changed -- I don't know why
you are not hearing sound now. The other possibility is
I note your card appears to have 3D sound capabilities
-- the documentation for the intel8x0 ALSA driver does
mention that this famous "Quirk" can result in the
swapping of Headphone and Master (which doesn't appear
to be happening in your case) OR MASTER AND SURROUND
settings. Try unmuting and setting volume for your 3D
sound settings.
Failing that, try IEC958 Playback AC97-SPSA (I don't
know what this is, it's time to fiddle now) or External
Amp. In each case -- amixer set <mixer setting>
<number> unmute. If neither of these work just work
down your list you got with amixer | grep 'Simple' and
keep trying aplay after each change and see if you get
something.
The fact you are not getting error messages (actually
have a look at the end of /var/log/messages [ do
tail /ver/log/messages] to make sure that's true, as
well as the output of dmesg), it doesn't seem to be
complaining about the device in /dev, and aplay thinks
it's playing, it's almost GOT to be a mixer setting...
I assume your PC speakers are switched on, and plugged
in at the wall and into the PC -- right? ;-)
