    Default Crackling, popping noise

    Anyone have any idea what might be the problem?

    I'd think it was a blown speaker except it only happens when the DAC is decoding from the optical input.

    Any thoughts?

    One disc or many?

    Sorry, streaming.

    I use the optical out on the TV to stream music services and of course anything on TV.

    Have you swapped out the cable yet to eliminate it from the equation?
    I love music. I want music. I need music.

    Too bad it isn't something simple like a cracked or chipped CD.

    If I understand correctly, the speakers work fine except when playing streaming music. My first suggestion would be to try a different cable, but again if I understand correctly, it works fine with the TV but just not with streaming music. That seems to eliminate the speakers and optical cable as the problem.

    If the receiver has just the one optical input and the TV sounds fine but streaming music that is processed by the DAC sounds bad, then it seems likely the DAC is the problem. Maybe you can borrow an external DAC with some additional cabling and see if the problem goes away.

    no

    I need to investigate further first because I don't think this occurs when I use the optical for the cable TV audio. So the issue may be in the ROKU.

    Plus, how can bad cable cause pops? Would it not just be lost information which would be patches of nothing????????????

    It might be a short in the plug you use to connect it, either in the cable or the Roku. Shake both and see if it pops. Optical cables are very sensitive to kinks. You can bend them around corners and ruin them. Same with HDMI. I'd try just swapping in a new cable.
