TVIP v605 - noise when changing channels

[orbitcluj]

Hello
I have opened this topic hopping that maybe someone noticed this problem as well.
I just bought a TVIP v605. Sound amazing, picture amazing but sometimes when I change the channels a 1 second "static" noise occurs. Sometimes it is strong sometimes not...
If someone had this experience and a solution pls let me know.
Thanks a lot.

Which audio codec is used in your channels?

hmm... I don't know... the bottom bar shows just the channel number, channel name and the logo.. how can I find the codec?
the problem is that noise does not appear to all channels... and the audio is set to PCM on both: the 605 box and the samsung tv...
