Brady, I don't believe that I've ever heard of a similar problem before, i.e., a delay of 10 minutes or so before the sound appears. It's almost as if the laser in the player which reads the SACD tracks(it operates at a different wavelength than for Blu-ray and CD)has developed a defect and needs to "warm-up" before it begins to lase, but again, I've not heard of such a thing.
I assume that you've tried the different audio settings in the player(e.g., PCM vs DSD)to see if somehow this has an effect, although time should make no difference in the effect that these settings have.
