Yamaha HTR-5730 Receiver - Page 2 Questions & Answers
Humming coming from the speakers
From all speakers?
How is the audio connected to the TV (be specific)?
Keep in mind that a TV is not generally an audio source as its programming always comes from something higher up the audio food chain than itself. Get the audio to your receiver from whatever THAT is, not the TV.
I'm only getting analog sound when tv is on,
Name the TV model and define the routing of said optical audio cable.
Digital audio is rarely originated at the TV but it usually comes conveniently from the source you're watching on it. Try routing the digital audio directly from the source to the Yamaha and bypass any limitations imposed by marginal TV electronics.

Audio amplifier IC damaged need to be replaced
Yamaha HTR-5750 no sound when I turn to the DTV/Cable setting
If you are not getting sound on "Any" input except "multi channel" you have a bad DSP chip in the receiver.In short, you need a new receiver, it's a 500.00 repair. If you get sound on "All" inputs except "DTV/CBL" You need to get into the main menu of the Yamaha and select audio, toggle to input, then DTV/CBL and select "Auto". If you still do not get audio, it would be due to the version of HDMI software in your receiver. If it's under warranty, Yamaha will update hardware and software for you at N/C. If it's out of warranty, use digital coaxial or optical as your audio input for TV and run your HDMI directly to the TV. (The repair for this too would run 250-350) I hope I've covered all the possibilities. If you need further help, post a comment and I can help you more.
