Default tracking and pause noise with 1541A

I have build DAC with EIAJ/I2S convertor and zero/1541A+5534i/v on Rotel951, but when i pause or track to/in songs i hear cracking noise (which i am shure that come from audio material in songs, not from any dysfunction in electronics). If its comon zerooversampling artifact or someone out there knows solution for this kind of problem, please help me.

If this was hard question, please reply to me any one you, who build zero-overs. (1543 or 1541) directly from Cd procesor unit like CXD...'s, or else EIAJ-out. procesor, or maybe and I2S-out procesor. Do you have experience like mine, or yours systems are working like standard units whitout any noise (audible and LOUD), without all that digital filters and so on. Thanks.

How is muting signal done? This could give al tracking noises, also the noises before a song begins.

Finaly i have credible solution to this problem. Just pickup the muting signal from mute leg of CXD** processor and feed that to base on any 50mA+ transistor, and put the collector to any relay circuit (ex. Mark Hennessy's "soft mute") on DAC's output, and you have "regular" DAC.
I am sorry 'Tubee' but i do not understand your answer (altought you are only member who answer me), but i think you are sugesting mute cicuit which i have described here.

I suggest a mute circuit in digital domain. From uProcessor(mab8461?) to mute of SAA7210. But if yours work its fine
