Until recently, my Wife was able to play and listen to audio CDs on her computer. Suddenly, or so it seemed, the audio CDs placed in her computer CD drives (a Sony CD-RW, and an NEC CD-ROM) played, but no sound came through the speaker system. All other sound sources (internet, computer generated, wave files, mp3s stored on the computer) played with out any problems. After unsuccessfully trying to determine the problem, it seemed unlikely that both CD drives would fail in this way at the same time, I decided it might be the sound card, which was several years old. I replaced the old card with a Creative Sound Blaster Audigy mp3+ card only to experience the same problem -- no sound is played from a audio CD. The audio can be heard when headphones are plugged into the jack on the front of the CD drives .

It still seems unlikely that the CD drives are both at fault. The more likely problem would seem to be of a software nature, but I am without a clue as to what may be causing the problem.

The OS is Windows 2000 Professional. The computer has two 400 mhz Intel CPUs, with 786 Megabytes of memory.

I do not know enough about the Registry to go into it with out specific directions, but could there be something in there that is "blocking" the CD audio?

It really is weird, and frustrating. All sound sources work. The CD drives work in all other ways. The audio can be heard from the front jack plugin, yet no sound emanates from the speakers!

It hardly seems possible that anything could be affecting the transmission to the speakers, IF the signal is actually reaching the sound card, unless, for some reason, there is a reason for this sound card, and the "old" one, to not be processing the signal.

Any help would be greatly appreciated

Thanks,

Steve

Hi.
Check the obvious - is the audio cable plugged into the back of the CDRoms. Open the volume control panel (speaker in the system tray) and check the volumes in there. Goto file properties and put all the tabs on. You need to ensure that SPDif in (for digital leads) and Aux (for analogue) is un-muted.

Other that I would assume it isn't a software fault (i.e. drivers) if it happened to both although I only use Win98SE and haven't seen any newer Windows.
