Hookup/setup question

[AbyssalLoris]

I've noticed that the volume drops by a large chunk when I switch between a regular channel on my TV (cable set top box) to a HD channel. My knowledge of AVR setup is minimal, so I'm wondering if there's some voodoo going on there.

The source is a cable set-top box with a HDMI out that is connected to the AVR (Yammy RX-V661) HDMI in. The TV is connected to the AVR HDMI out. The front L/R speakers (the only ones I have at this point) are connected to the appropriate speaker outs on the AVR. Any clues?

Are you comparing SD loudness to HD loudness from the same source (the cable set up box)?

If so this is actually more likely due to the channels you are watching. Some channels are aired more loudly than others. Sometimes this even happens with between shows on the same channel and even between commercials.

If this is between two different sources like a cable set up box and an antenna you can use you AVRs options and actually adjust the loudness of each source in the menus making them either louder or quieter.

It's just the level difference between different program material on different channels. With my cable, the stations that broadcast only analog audio are far lower in level in than the digital channels.

So, always turn the volume down before changing channels, or sources.

The audio level on the channels themselves may be different as you guys suggest, and it if that is the reason, it is very annoying indeed. But isn't it too much of a coincidence, as it happens to all HD channels, and HD channels only (as compared to SD channels)? Everything is from the same source (set top box).

No such thing as too much of a coincidence; it's either a coincidence or it isn't. There's also the option of it being a conspiracy, but in who's favor? Either way, I think you will become intimately familiar with the mute button on your remote, eh?

 

[AbyssalLoris]

Yes. I stand corrected. It is a coincidence.

In fact, it might be a conspiracy. A conspiracy by Comcast. I'm always willing to believe that.

Yes very annoying; I can look past it when I am watching "normal TV'' but when I switch to bedroom mode to watch the final hour it drives me crazy.

If it was as easy as turning the volume down before you change channels or using the mute button then you are not an audioholic as we are too lazy to use more than one remote or use the TV to change input source much less hit a different button to change channels...

I'm revisiting this because I have an update. There is definitely a problem. It is not just signal level variation with channel.

I was watching some nature type program on a HD channel and I noticed that the volume goes up and down randomly. All connections are pretty solid. The sound just keeps going in and out. This only happens on HD channels.

I'm beginning to think the AVR has some issue with decoding HD audio. Now I don't know anything about what the HD channels broadcast. Do they use HD audio? The AVR is a Yamaha RX-V661. The cable box connects to the AVR by an HDMI cable and the AVR connects to the TV and speakers using an HDMI cable and speaker wires of course.
