dodgy sound from cd/dvd drive

  robbiemac 16:44 20 Sep 2006

The sound quality from my combined CD/DVD drive has suddenly deteriorated, resulting in scratchy, slightly distorted sound from any disc, whether audio CD, CD-ROM or DVD (picture quality on DVD is fine). I can rule out the problem emanting from my Creative I-Trigue 2:1 speakers, because sound from digital files remains perfect; and the same problem occurred when I disabled the Creative speakers and used those on the monitor.
I've also tried using a CD-drive cleaning disc without success.
Whether this is relevant or not I don't know, but I noticed some time ago that the PC (running Windows XP) no longer displays an intro screen automatically whenever a disc is inserted into the drive. I need to open the window by going into 'My Computer'.
Needless to say, any advice or suggestions gratefully received!

Do you know what sound card you have.If not,run Belarc,this should tell here

Try updating the drivers from the manufacturers site.

In device manager right click drive slect properties (use tabs to check functions) check if CD drive in DMA or PIO mode, DMA is better.

Do you have a cable from drive to sound card?

Again in device manager check that "Enable digital CD audio for this device" is ticked

Autoplay Repair Wizard click here

Autoplay disable/enable
1. Click Start, click Run, type regedit in the Open box, and then press ENTER.
2. Locate and click the following registry key:
3. To disable automatically running CD-ROMs, change the Autorun value to 0 (zero). To enable automatically running CD-ROMs, change the Autorun value to 1.
4. Restart your computer.

Skidzy, you're a star! That worked a treat - many thanks. The volume output seems slightly lower at any given level (even though the various control panels are all max'd out), but I have perfect audio again so I'm happy.

Fruit Bat - thanks for your advice. One of the settings was indeed in PIO, so I changed it. I haven't had time to run the Repair Wizard yet, but will certainly give that a try.
