Audio switching in/out

[mikegunnz]

Hey guys, I have a question regarding the audio when I watch tv. I've got a scientific atlanta through cablevision, yamaha receiver, hooked up to a panasonic plasma monitor. Periodically(3-4x a week) I'll be watching something on hdtv and the sound will cut out for a sec and the receiver will switch from dolby digital to pro logic. This happens more often with hdtv although it has happened a couple times while watching sd channels and receiver will cycle through like it switching throught different audio(prologic-digital-etc)
It doesn't happen that often, but its a little annoying. I can't figure what the problem is. It only seems to happen when watching tv, not dvds or playing wii. Could it be the cable box?? Maybe the digital coax?
Any suggestions would be appreciated.

You don't say how your audio is routed to the receiver. I have Cablevision HD service and they just drive me crazy sometimes with their different annoying quirks, like signal dropouts, boxes rebooting in the middle of watching a program, loss of advanced services, etc. I suspect that the cable audio signal is cutting out for a split second and the receiver is searching, trying to detect the type of signal (if your Yamaha works anything like my Onkyo receiver).

(if your Yahaha...

What's a "Yahaha"? Sounds funny.

its hooked up through digital coax. If others experience it too, then maybe its not my equipment and just the service. It only happened when watching tv so I figured it was either service, cablebox, or the digital coax from the box to the receiver.
