Hello,
I am using Enterprise Linux 4 , whenever i make a mistakes , sound does come from my speakers but when i insert a music CD, it shows that it is playing but i can't hear any music

Help

Make sure you get the mistake sounds from your external speakers through your sound card. Some times the PC speaker gives the eror sounds, that does not mean it can play your audio devices.

What mixer do you use?
aumix, kmix, ... ?
They normally have an extra slider for CDs.

It's not uncommon for systems to initially set up with the mixer muted.

Actually the Sound card is good, cos when i was installing linux, It played some sound through the speakers and asked if i heard it,which i did

Its not Muted , I checked to make Sure

You have to manually check the "Enable External Amplifier" check box in your sound setting. I have a Fedora Core 4 install on my Dell laptop and had the same problem. I found the answer using Google.

You guys using ALSA?

Pipe something into /dev/dsp and see if you can hear it.

If not, try alsamixer.

echo "234028304928034829038490283904" > /dev/dsp
