Audio has a whining noise when connected through Bluetooth
When connected to my Blackberry through Bluetooth, the speaker has a high-pitched whine that accompanies the sound. Does it have this same problem with other bluetooth devices? Is there anyway to fix this?
Re: Audio has a whining noise when connected through...
Hi, I also own a Yamaha nx-b02 unit. Mine whines too, but only when connected via Bluetooth to my Vaio f series or my friend's htc. They work perfectly on my older Toshiba laptop wich is equipped with Bluetooth 1.1. I suspect the problem only occurs with Bluetooth 2.x equipped devices. (might be wrong though) Can anyone else add their experiences please?

The basics, your battery is used to provide power to the starter. Once the engine is running the alternator then provides current to recharge the battery and run all of your electrical components. so I would suspect the starter is not working to start the engine.
This sounds like alternator whine. Do you have the power and ground connected to your battery, or through the accessory power? Make sure the power and ground wires are sufficient size, and connected to your battery, and make sure you have the power wire fused no more than a foot or two from the battery. If it is only on the right channely, maybe this wire is getting feedback from another wire. Seperate the wires if this is the case.
Wires create magnetic fields, and if a speaker wire is next to a power wire or something, you will hear a noise, typically high pitched whining.
Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).
i have the same problem with the RZ-4900AV,
it manifests itself when any video application runs through either the optical or coaxial input.
in my case it's definitely not the optical cable itself, which works fine on another receiver.
optical or coaxial input of audio CD's is fine, but a DVD video on the same DVD player gives the high pitched whine. the same with the PS2 on the optical input, audio CD in the PS2 no problem, PS2 game or DVD video gives the whine...
i think, unfortunately, it's a crap receiver...
and i solved the problem by buying a RZ-6900AV, which works perfectly in exactly the same environment.
