Sound Problems in Fully Updated 8.04

Sorry to take so long but winter creates pressing tasks and the computer in question is in someone else's cabin. She is happy using XP though her installation has already been invaded by things that really slow it down. I'm trying to persuade her to use Ubuntu but the lack of sound for movies deters her!

Hi Roger. Win XP plays sounds, so there is no problem with the soundcard. As
it's an older machine, I would expect the soundcard to be supported with
linux, so would you post a bit of info for us. The output from the following
commands, as user, which are listed below.
lspci -v (just the part for the soundcard)
lsmod | grep snd
If you have anything plugged into the usb which may be sound related,
(webcams, usb midi keyboards, etc.) remove them, as the usb starts early in
the boot process, and sometimes these devices can interfere with the actual
soundcard being set as card0. the usb devices can be sorted out later.
Often times the sound is deliberately muted so that you don't damage your
ears, or speakers, so open alsamixer as user on the CLI (terminal/Konsole),
and see if anything is muted, or sliders down at zero. The "M" key toggles
Something else that comes to mind as I have Kubuntu 8.04 installed is that
pulseaudio may be entering the equation, and causing problems with the sound.
Kubuntu 8.04 doesn't have pulseaudio installed as default, but I believe that
Ubuntu does. You can easily disable it by doing an apt-get remove
alsa-plugins-pulseaudio. You can always re-install it later, if you want to
use it, but temporarily removing it at least takes it out of the equation if
you have problems getting the sound working.
Something else to check is /etc/group, and make sure that your user name is
there for the "audio", and "cdrom" groups. I havn't had a problem with that
with Kubuntu, and only on some early Debian versions did I have to
specifically add my user name to those groups, but it's worth checking.
That's all I can think of for now. Please post back the info I requested.
