No sound from CD (CDRW), but okay for everything else.

Sound for wav files etc is working from my external speakers.
Sound Card Configuration / Detection - Plays sound test okay.

Gnome CD Player originally said device is /dev/cdrom, can see tracks and appear to start and count CD as it plays but no sound. It lists the name of the tracks okay. Tried changing Gnome CD Player to /dev/scd0, still no sound.

Have both a DVD and CDRW.

Is the audio cable from the cdrom to the sound card connected?

Is the audio cable hooked up?

maybe it's a bad cable

Both CDRW & DVD sound work okay on another non Linux OS. So cables are okay.

do they play in kde in kscd?

I have been told that in linux the cable HAS to be connected to sound card. Linux works different than other OS's

you need the cable for all the os s not just linux

No sound in kde in kscd either.

Cables? I don't under stand what you mean. Both DVD and CDRW are sending sound to the sound card, when used with non Linux OS. Sound going from CDRW to sound card to sound card output port to cable from that port to the speakers. Works okay, but not in Linux.

Everything is inside the PC box except the wire to speakers, which does work except for Linux.

What's the 'other OS' you mention? If it's Windows that came preloaded on your PC, and you bought it from a dodgy manufacturer like Compaq or Tiny, it's more than likely that CD audio is being played through software instead of through hardware.

To see what I mean, take the side off your case and check that there is a small cable running from the back of your CDROM to the sound card (or somewhere on your motherboard if you're using onboard sound). It'll probably consist of three thin wires connected to thin black connectors at either end. Don't get it confused with the IDE cable which is a wide ribbon cable.

If that cable isn't there then while you're in Windows, CD audio is being played by reading off the data from the CD in software, mixing it with any other sounds that are playing, and sending it to the sound card. Needless to say this is a huge waste of CPU time, but a couple of manufacturers are so stingy that they'll do it this way to save a few pence on a cable. Linux doesn't support this loopy method of playing CDs natively, but I think there's a driver for XMMS that will do it for you.

THANKS! I will open the box and check this out. Hopefully I can just add the cables. (WinXP/Compaq)

Have you tried to turn up the volume controls

try aumix

if you have the cable and the volume is up try running sndconfig

Speakers and all volumes are up, nothing on mute on Gnome Volume Control 2.0.0 mixer for sound devices. I assume this is the same as aumix.

Sound Card Configuration / Detection - Plays sound test okay.

It is. A certain someone didn't read the thread before posting

Let us know what you find once you open the case.

I opened the box and there are no sound cable connected. Just the IDE cables (wide ribbon cables) and the power cables. The DVD has an unused Analog output and the CDRW has an unused Digital and Analog output. Everything is built onto the mother board, sound (SoundMAX Digital 82801DB AC (Intel), graphics (Intel 82845G/GL). The only card is the modem card.

Thanks for everyone's help.

there should be at least one place where you can connect an audio cable (it is black and has a very thin, flat shape.

sometimes there is only one place to connect it to the motherboard so you have to choose either your dvd or your cdrw (most would pick the dvd rom)

if there are two places to connect audio cables on your mobo then you can connect both obviously. check the mobo configuration by looking at the manual or looking it up on the net and you will see where the sound can be connected.

best of luck
