Hi Alan,
Sorry for the late reply. I have lost access to the pc that was similar
to your setup so I will not be able to do any experiments. My replies
are below.

It is my understanding that alsamixer and amixer do the
same things, alsamixer being a graphical(ncurses) interface,
and amixer command-line. Am I wrong? I can send a picture
of the alsamixer interface, if you think it would help.
[prashant] That is my understanding too. The picture would just easily
tell you if the outputs are muted. If however you are at ease using the
command line interface, that is fine too as long as you figure out if
you are muted or not.
I turn my computer off every night, and reboot in the
morning. This morning after turning the computer on I
immediately checked my /var/log/ hoping to find out
what messages were given by the boot process. Here
are the results of grep pulse * that bore a
date of Nov 11

messages in syslog about pulseaudio

[prashant] Unless you really need pulseaudio why don't you remove
pulseaudio for debug purposes (
apt-get remove pulseaudio ). You can always reinstall it.

<G> I believe so. I confess that I am very much in the
dark still. I am certainly using HDMI. If I have an
asound.conf, I haven't found it.
[prashant] Is your sound going out through the video cable or via a
different audio jack. I made a new asound.conf and put it in my home
directory. This changed my default audio out to the audio jack instead
of hdmi. You could do the same like so:
vim ~/.asoundrc
pcm.!default{
type hw
card 0
device 3
subdevice 0
}
You would have to figure out the card and device. I do not remember the
commands I used to figure those out and unfortunately as I mentioned
earlier cannot experiment on the hardware.
Cheers,
Prashant
