I continue to have sound problems. You suggested that I adjust the mixer
settings in LXDE, but I can't find them. My LXDE was installed from the
Debian repository, either during the network installation (if it gave me
the option to select it, I don't remember for certain) or immediately after
with an apt-get install command. When I use the lxsession-edit command, none
of the options listed have anything to do with audio.
LXDE comes with tha LXMusic program for playing audio files and it comes up
loaded with a short sound file, but there is no sound when I play it. The
Preferences screen in LXMusic shows this under the Audio tab:
Output
Plugin: Advanced Linux Sound Architecture
Device: default
Mixer: PCM
Buffer Size: 32768 KB
After looking at additional web pages about sound problems with Debian and
LXDE, I found the following facts, which show that some alsa packages have not
been installed but should have been. These facts are all about the responses
I get on my laptop after installing Wheezy and LXDE.
The command dpkg -l | grep alsa finds bluez-alsa:i386 and xmms2-plugin-alsa
but no other alsa packages.
The command dpkg -l | grep PulseAudio finds only libpulse0:i386.
The command dpkg -l | grep mixer finds nothing.
The web pages I looked at suggested several commands to try, but I found that
the following commands are not found by the Bash shell.
aplay
alsactl
alsaconf
/sbin/chkconfig
While several of the web pages suggest installing a package like gnome-alsamixer
or some other package, I have not seen any web page that suggests that the
normal procedure is to manually install a mixer package after installing LXDE.

So a sound driver is loaded.
The install appeared to go well. I chose the LXDE desktop environment and
installed Midori and SBCL. But then I discovered that there is no sound.
There was an error message on booting that said that pcspkr was already
registered. I added the blacklist snd-pcsp line to fbdev-blacklist.conf and
that fixed the error message. But there is no evidence that anything
associated with alsa was installed. For example, /usr/sbin/alsa does not
exist. Even vi does not beep when you expect it to.
This depends on the configuration of the terminal emulator.
I would expect that
Wheezy would come with the appropriate sound software installed.
I am in the audio group. When I look in /dev, I don't see anything like dsp
or pcm.
[...]
/dev/dsp is ancient history (OSS). ALSA sound devices appear under
/dev/snd.
In a fresh installation, the initial mixer settings are likely to be
silent (or very quiet). I expect that LXDE has a volume control or
mixer application you can use to adjust them. Let us know whether you
continue to have a problem with sound.
Ben.

Always try to do things in chronological order;
it's less confusing that way.
