CD player producing unbelievable garbage at the output (see pics)

[Elias]

Hello,

I made a test CD for audio testing. It contains for example short noise bursts. When playing the CD with my oldish Yamaha CDX-593 player, I've noticed some wierdest things at the analog output. It's totally garbage!

Here I play the CD with the Yamaha and record the line level signal with laptop audio input.


See this picture, there is a miraculous DC shift occuring just before the noise burst!

And this even worse, See after the noise burst the signal peaks and slowly comes down:

What is going on??

The CD is okay, since with another player nothing like this happens.
