Just as a point of reference, I run my video and audio from my Tivo HD through a Denon Avr-1611 which feeds my LG tv.
It could be that the sound problem might be in an isolated loop or loops.
Has anyone tried to tie it down to which areas had this problem and which didn't ? Or what kind of equipment they are using ?
I hate trouble shooting but that would be the first thing I'd try to find out and try to narrow it down from there.
Anything is possible, but if you still have the recording, or maybe with tomorrow's game if could you try the following. Listen to the audio with the standard DD setting on the TiVo(you're still using one I hope) and pay particular attention to how the announcers voices compare in volume to the volume of the crowd. Also check to see what sort of output you're getting from your surrounds. Then change the TiVo output to PCM(and/or an analog output for other devices like a cable STB) and recheck the surrounds for output level and see how the announcer's voices stand out a bit more from the crowd, it should sound a bit more "open", and you should have increased output from the surrounds. What myself and the other posters quoted above are hearing is a collapsed dynamic range, a compression being done to the signal that results in everything sounded as if it's at the same gain, whether there's a homerun or absolutely nothing happening at all, the crowd noise stays basically the same. If you've ever felt pressure on your ears when you increase altitude, the feeling is very similar to what I hear/feel when listening to CSNBA broadcasts. It also sounds as if there's a pulsing action to it, when the announcers voices come in, the crowd noise will lower just a bit, but when they're quiet the crowd noise will resume at the same loud level.
Another example is pick a prime time drama from KPIX and then another from KNTV and compare the dynamic range between the two, the KPIX show has very similar characteristics to CSNBA in that the audio level stays pretty much the same no matter what's happening on the screen. On the other hand, the KNTV show will have a much more open sounding dynamic range, you may have to set the gain a bit higher to hear the quieter parts, but when something happens, an explosion or a scream, you hear it above and beyond say someone casually asking what time it is.
It's like the difference between listening to AM radio and a CD, that's what I and the others are hearing and it shouldn't be that way.
AT&T Park can be a noisy place no doubt, but with a proper audio setup it should still have some dynamic range, you should be able to tell something has happened without looking at the screen, right now you'd never know without seeing it happen as it all sounds pretty much the same.
The above is assuming that one is feeding the DD 5.1 output to a like capable AVR and utilizing a setup of 5.1 speakers or more.
(P.S. I just noticed that you're feeding the TV from the AVR and as such I'm guessing that you're not running your audio as I've described just above in which case you wouldn't hear the issue I'm talking about as you likely only getting 2 channel audio anyway.)
(P.S.S. The Dodgers are 8 and 1 and Kemp is mashing the ball better than he did last season!
