I used to get this when I used 'cheap' CD-R's ... ones made in China or Taiwan. lol The cheap disks sometimes played ok at first but within 6-12 months would got distorted or noisey. Buy decent disks.

Check the music before you burn it. Does it sound ok on the computer? Does the disk sound ok on the computer if you play the CD through iTunes?

Burn at minimum speed your disks allow. Even though my burner can burn at 52 speed, I buy medium speed disks, burn at around 4 or 8 speed.

Are you using CD-R's or CD-RW"s? Some stereo systems nowadays can play CD-RW's. As can some dvd players. However the reflectivity on RW"s is so low it's more difficult for most players to detect it properly & read the disk info portion to know where to start or where each song stops, etc. thus skips or does not play at all or possibly noisey.

Hi. Thanks for your reply.
I am actually using Sony writable CDs (CD_r 700MB), I had a pack of 50 of these, and the first few I burnt were ok, but recently every one has been getting this sound on them. So, I wouldn't say these were particularly cheap.

I have been burning at 8 speed, so I will follow your advice and try to burn at an even lower speed and see what happens.

If this doesn't stop the problem then I don't know what else to do.
Thanks for your reply.
