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.
