Your CD port is probably broken.

Check the cd types that that system will play. Depending on the type of recorded material, some CDs won't play on certain systems.

Check the mode of operation. There can be a setting where it just plays one disc. Random or mixed will give you more songs to get to other discs.

That is not unusual For some cd players to do that,

If it is just a standard cd player it will only play audio cds.

CD players commonly will not recognize some types of CD, eg MP3 recordings, or maybe CD-RW recordings.

However if this is happening with CDs that would previously play OK, then it could be

- scratched or dirty CD surface
- contaminated laser lens in the player
- laser lens has become misaligned

The last 2 need a service technician, but it may be cheaper to buy a new player.

Switch the channel on the phono to isolate the problem within or outside of the amp.

To resolve this issue, try one or all of the following:

• The Wave® music system is designed to play commercial CDs, CD-Rs, MP3-encoded CDS and CD-RWs. If your system has trouble playing MP3 CDs, make sure the discs were recorded with compatible formats. See Cannot play MP3 CDs



• The system may not be able to play certain CD-RW discs. Playability is dependant on how the disc was recorded, including the format it was recorded in and the actual disc used for recording.
  Note: iTunes defaults to AAC as the encoding format. In order to use iTunes to make CDs that will play on the Wave® music system, you’ll need to change the format to MP3 How to Choose Import Options



• Different brands of CD-Rs and CD-RWs use different materials which may affect the ability of a player to read them. If you are burning your own CD-Rs or CD-RWs, experiment with different brands of discs



• If a commercial disc won’t play, check for scratches, fingerprints or other physical damage. Try the CD in another player. If it still won’t play, there may be a problem with the disc



• Reset the system by disconnecting the power cord from the wall for one minute, then plug the system back in
