Hi,

Hello - you need to go to System>Control Centre, and then select Sound System. Select the Hardware tab and next to Select the Audio Device choose ALSA (Advanced Linux Sound Architecture. There are other sound systems you could try, but stick with ALSA for now.

Enable full duplex sound under the same menu... Now try your speakers again. If you don't hear anything you could try opening a terminal (command line) and typing: alsamixer . Turn everything up, and use your arrow keys to scroll left/right. Hit Esc. when you've finished. That might work.

Please let us know how you get on.

also in a terminal make sure that alsa-utils is installed by running apt-get install alsa-ultils and then run alsaconf.

My system is configured to advanced linux sound architecture & i made it full duplex as you have told BUT NOT working.

alsamixer: function snd_mixer_load failed: Invalid argument

This is what i am getting when i tried alsamixer

I have no clue what the ALSA errors mean. Do you have any idea which sound card your system has? You could try using this command to find out. If you don't understand what you are looking for, then paste it back here for help.
(as root or sudo)

lspci

Also paste the output of this command too please.

lsmod

It's possible that ALSA is looking for a certain kernel module, producing that error when it can't be found.

This might not be easy to fix, but I would become root and do:

lsmod | grep snd

That will generate a list of all the installed sound modules. You might then try:

rmmod snd_hda_intel
modprobe snd_hda_intel

Assuming that the above module was running anyway. The idea is to remove it, then re-insert it. I got the idea from a Google search, but it's worth a try. Something is missing from your system, and a module seems likely.

when i try to remove module using rmmod it says module is in use & cant be removed
