Since the last software update (with Caller ID being turned on)I have about a 1 in 4 chance of being blasted by a waterfall-like noise when I change channels on the SD channels.

I keep the 6000 on Hi-Def output and my audio is via the fiber optic cable to my receiver.

When it happens, I go up a channel and then back and it goes back to normal most of the time. Sometimes I have to do it twice.

Anyone else have this problem?

In a previous thread describing the changes in the new code, I posted my observation that the 6000 now "winks" the optical output every time the channel is changed. The side effect on my receiver is that the on-screen display shows "Pro-logic" or "Dolby Digital" after every channel change, where it previously only displayed the mode when switching from ProLogic to DD or from DD to ProLogic.


My guess is that your receiver is having problems resynchronizing with the datastream after each wink, and the waterfall sound is digital data being misinterpreted by your decoder.


Going into full blown speculation mode now, I'm guessing that some people were having problems losing audio sync caused by dropouts from weak OTA reception, and the "wink" was added to give these people an easy way to re-sync and recover their audio just by changing channels.


In any case, I'd suggest that you give a Dish CSR information about what equipment you own, and try to get them to escalate the problem to engineering.

I am getting the same problem on the local Fox affiliate here in DC. On my SD OTA channel the picture stays rock solid but sometimes the audio goes wacky like a loud waterfall or static. It's VERY annoying.

I think I'm having a similar problem. Since the last upgrade, every time I switch to an HD channel (HBO-HD, HD-Demo, local digital network affiliates), my audio completely cuts out. I have to switch to a different audio input on my Denon receiver and then switch back to the optical input from the 6000 to get sound again. I think the Denon doesn't like the "winking" of the optical stream.

I've talked to them about the problem, but we just went over some basic trouble shooting. I'm going to give them a call tonight or tomorrow and get in touch with the 6000 specialist who is supposed to be on duty and try and nail down the problem.

Darian you might be right about the cause but it NEVER happened AT ALL before the last upgrade. I also sometimes get the no audio at all problem.

Hey guys. I am in the DC area. It is your preamp losing sync. Different receivers/preamps handel dropped signals differently. As a custom installer I get to play with lots of other people's gear. The problem is completely linked to the processor that looks at the optical in. The noise or waterfall sound is when the wrong DSP is applies to a format. DTS used to do this on lost of processors. Once the processor figures out what it is looking at... DD, dts, PCM, MPEG then it has to apply the write codec. Once this is done you get sound.
