During television programming the volume fades and comes back
I have direct TV but when we installed our new audio receiver and bought a new hd samsung plasma we started having volume issues. the volume will periodically get louder and softer. some days it does more often than others. what's up with this?

HD Video FROM your TV???? Video goes TO the TV and gets there either via direct tuning of an HD air station or from a Cable?SAT box, BluRay player... The unidentified TV's manual should cover that.
The Onkyo's manual covers most of the rest.
NO signal ever benefits from multiple connections or 'hops' and it gets expensive zig-zagging a signal all over the room. K-I-S-S is the word of the day. Run the BEST version of any signal directly from its source to the BEST electronics that will present it to you for consumption. The separation of audio and video inputs and outputs on a device is what allows and ENCOURAGES the routing of each signal to the BEST electronics that can process it. Example: your TV does not have the best speakers in the room so why send it any high-end audio?
If the sound actually comes from an external source treat that source like any other hi-end audio component and attach its highest quality audio directly to the receiver according to ITS manual. The separation of audio and video inputs and outputs on a device is what allows and encourages the direction of each signal to the BEST electronics that can process it.
If you're expecting multichannel sound FROM THE TV instead of from the source you're watching, it's not gonna happen. TV's are notoriously poor sound sources. This one is no different.
Multichannel TV-related audio is best found at its source - cable / sat / dvd / bd....
I run video-related audio from my video sources directly to my TV and their audio directly to my receiver. Specialization yields best results.
I'd recommend skipping the Receiver for video, too, as it adds a lot of opportunity for HDMI-related incompatibilities and sound syncing problems. The more interconnects in the path, the more distorted it will become and the more opportunities for problems. Plus you can bypass the receiver and listen to lo-fi programming like news and weather through the TV's speakers if you like. Save a buck on electricity.
Just curious, which HDMI on the receiver is connected to your TV? Input or Output?
This note is on Page 11 of the manual:
Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video monitor. To enjoy the sound from speakers connected to this unit,
-- make an analog or digital connection besides the HDMI connection (see page 13).
-- mute the volume on the connected video monitor
"Check SP cable." -- The unit is perceiving a short circuit. Are your speaker impedances sufficiently high? Disconnect the Front Right speaker and try raising the volume again. The speaker may be blown or the cable shorting.
I want to think about this for awhile but first I want to caution you to NEVER turn the volume all the way up and then place your ears near the speakers for diagnosis of an unknown problem. If you inadvertently affect it to come back you can kiss your speakers (and maybe your ears) goodbye.
I'd agree that it is none of your hardware if it affects all inputs, two receivers and multiple speakers.
This sounds like a good one.
The simplest source to use for further trouble-shooting would be FM as it has no external connections, and it's vanilla stereo. Keep It Simple.
"Power bars"? Do you mean like a power strip with multiple outlets and maybe some kind of surge protection? Pare the system down to its most basic form - receiver, front speakers, one power source direct from the wall. What happens? Add components and complexity until the problem returns. Good luck.
I have a TX-SR505 and the same thing has been happening on mine since I bought it. I am also hooked up to a Panasonic Plasma, using the optical cable to the receiver. It's been perplexing me. I have noticed it typically during commercials, not during normal programming. If I turn up the volume on the Panasonic TV, I can hear the audio, so I know it's not a problem with the over the air signal. It must be something wrong with the reciever. Would love a fix to this!
Your HDMI version software and hardware will not work with todays version. The current version 1.3b is what works correctly (so far) IT can be upgraded to todays specs however, it's a preicey task for minimal gain if you are viewing any TV smaller than 50". The human eye cannot see the difference between 720p and 1080p on any TV 50 or smaller. That being said, if your TV has multiple HDMI ports, you can sidetrack this issue by connecting directly from the source, ie DVD, BLURAY, etc. then use optical or coaxial digital coaxial to the receiver. I know it's not the best news!! don't Blame Yamaha! it's been the recording industry and copyright protection issues that have overloaded product with "anti-piracy" software to the point you can't view it!. All receivers prior to 09' have multiple HDMI issues. Also, try setting your receiver to "Auto" in audio and running an analog RCA from the source to the receiver as well as HDMI, it may help, however, analog is much louder than digital, and I'm not sure if you can "offset" the volume level for analog in that receiver's settings. So, when you go to a commercial it could be unbearably more annoying than not listening to the commercial at all! Hope this helps.
There are two reasons for this. Firstly, the commercial channels are deliberately boosting the volume during commercial breaks to grab your attention. Secondly, the commercials use compressed audio (narrow dynamic range). This often comes across much louder than program material, which is using a wider dynamic range on which you would have based your volume setting. It is noticeable that the BBC are also sending out wide variations in volume at present - Yes it is VERY annoying. Some sort of ALC (automatic level control) is required but this would need to be switchable. Hope this helps.
