It's important to note that:
* All PS3 models can play DVDs.
* Some older PS3 models may not be able to play CD audio discs. The ability to play CDs depends on the specific model and its firmware.
* You can check if your PS3 model supports CD playback by looking for the "CD" icon in the media player.
If you're unsure about your PS3 model, you can consult the PlayStation website or the user manual for your specific model.
