DVD Player.....I am stumped.....

Hi,
I just bought a cheap Samsung DVD/SACD for the video conversion, and to try new audio formats, I initially hooked it up as digital coax.

Sorry this model is HD841

Anyway, I got this real weird digital chirp sound, so I took the unit back, it would play for a bit and kick on, and sometimes it gave the chirp right away.
So I traded it in, got a new one home and same thing, so I switched coax input on Rotel pro, same thing, so again I switched, this time to Digital Tosslinnk and same thing, Now I have had 5-10 DVD Players, hell way back I had 2 laser disk players...and Never had a problem, it is not my Pro..because my Sony was fine before...I check and triple checked all settings on both DVD and Rotel...and I cant for the life of me found anywhere where I am at fault..so anyway I am stumped, please help! thanks Chad
