Hi Karl.

As I seem to be on a roll at the moment, with helping folks with sound 
problems, let's go for it.

First, to check that nothing is muted, open Alsamixer on the CLI (Konsole), 
and check that no controls are muted, and sliders like Master, PCM, Front, 
and CD are up.

You may have to set a model option for snd-hda-intel to get the sound working 
on your machine. Open Konsole, then, sudo kate (or kwrite if it's installed), 
then navigate to /etc/modprobe.d/alsa-base. Now add the following line to the 
alsa-base file.

options snd-hda-intel model=acer-aspire

Save the changes, and reboot. Open alsamixer again, and make sure nothings 
muted and the sliders mentioned above are up.

Usually I check out if the sounds working with an audio cd, and Kscd, but you 
usually get sounds when logging in, if the sounds are up and running.

Let's go with the stuff above for the moment, and see how it goes.

You could also post the output of the following commands.

cat /proc/asound/cards
cat /proc/asound/version            (this should be 1.0.17)
lsmod | grep snd
lspci -vn      (just the bit for the soundcard)
grep ^Codec /proc/asound/card?/codec*

All the best.

Nigel.
