If the problem is not the actual D/A converter, I would suspect the buffer transistor at the outputs. For this vintage of player, there sould be a couple of to-92 transistors just prior to the audio output jacks. Check/replace those.

**VERY unlikely to be buffers (without looking at a manual). In most
budget machines, the To-92 devices are muting transistors. In higher
quality units, relays are most often used. VERY few CD players used any
discrete components after the last OP amps (apart from the muting
transistors).
