Well it’s informative that you’ve mentioned it, but the SC-2900 has ended production several years ago. While Denon have made updates to some models after their end date, it’s fairly unlikely that a possible CD bug would get looked into and any firmware released for an SC2900 now, in 2022.
A lot of CD playback issues can normally be attributed to the CD surface or track itself - as both those things can affect how playback is handled.
