Disappearing Audio

Use Adobe Audition to create subliminal CD’s – then use Nero SmartStart to copy and write protect on 80 min 48x multispeed CD-R. Use Sharpie permanent marker to label contents. CD plays over and over with excellent quality sound on both digital player and computer, but mostly on digital player. Then, one day, when trying to play, there is just nothing at all on disc. Has anyone had this problem or know what might be causing it?

Thanks much ; mockadean

It’s already there, but either the disc itself or the player/lense should be cleaned or there is a hardware issue…
