Last night I was watching/listening to UPN. All
of a sudden the audio ramped to a very high cracklying
level and then dropped back down to normal listening
level. This happened twice.
What device delivers UPN to your audio/video receiver? Do you have a digital AND analog connection, or only one of them? Incidentally, I assume this was not HD because you did not say UPN HD...was it HD? Satellite or cable? Antenna?
It was a crackle sound and not like the audiotrack
itself had been boosted. But did appear to be
coming from the speakers.
If the sound were of such a high level that the ends of the woofer voice coil forms smacked against the magnets, you would hear a crackling. I have heard this, and it is pretty awesome (in a bad way).
Of course the better half thought the sky was
falling in.
Please assure her that it was, but only a very small slice of it.
I have also noticed a crackle when the scene changes
quickly but was told that this was a Plasma
phenomenom.
This makes me think you are using a mid-1980s cable box. See my first question. And I can't imagine how the plasma could be in any way related to a crackle, so I would love to see a reference on that.
This time it sounded more like audio and the video
screen did not change.
I am sure it was just audio.
Does anyone think it was a broadcast signal scramble
problem ?
It probably was. A call to the cable company (DirecTV?) would be in order to see if they have had any audio problems.
I am not using a secondary amplifier. I am using
the built in amp and speakers which is all part
of the Pioneer Plasma display.
Ah. THAT is why the crackle could be related to the plasma; it is not a problem with the display, it is a problem with the television. I assumed you had a display and a separate tuning device, so now I gotta ask: is this a TV and you are using the plasma TV's internal tuner to get basic cable? Is this a plasma with a built-in HD tuner (I don't know if they exist or not)?
And I will add that I watched that HD miniseries
about Rome last night on another channel and had
perfect picure and sound.
Hmm. HD. From an internal HD tuner, or from an external satellite receiver?
