I just helped a friend put together a moderate home theater to go with his 50" Samsung DLP. For a number of reasons we/he chose to go with the Onkyo TX-SR702 which seemed to be a solid choice. He's been having a problem with digital sound from his cable box. Here in NYC Time Warner utilizes the Scientific Atlanta 8000HD, which is also a DVR box. We've used the coaxial digital audio output from the cable box into the Onkyo (this box also has optical). Here's the problem: when switching from one channel to another, the digital audio signal drops out (which is normal). When the receiver losses the digital signal it searches for an analog signal. There is a loud clicking noise when it switches from the digital to the analog (and also when it goes back to digital again).The noise definitely comes from the receiver (as opposed to the speakers), and we've confirmed with Crutchfield that the unit is not defective, as their bench unit behaves in the exact same way. Needless to say it's very annoying to watch TV as this happens everytime they change channels, and it clicks twice, once when it loses the signal (and switches to analog) and again when the signal stabilizes and it switches back to digital. The Onkyo doesn't let the user select digital only (ie: never switch to analog when the signal drops out), and changing to the optical cable doesn't change the situation. Other than switching to analog audio inputs (and obviously losing fidelity) I can't come up with a viable work-around. Has anybody else experienced this with Onkyo before? How about other receivers? It seems like a fairly common thing, and if the Onkyo is well known for this apparent design flaw, what other brands exhibit the same loud clicking? Going digital-analog-digital wouldn't be too bad if they could avoid the loud clicking, there would just be a pregnant pause of silence. I've recommended Onkyo (and Denon) to a number of friends in this $500-800 category, and I hope I haven't been blind to something like this, especially if it's well known. Hope there are others with similar experiences who can lend a hand. Thanks in advance.
