I bought this device to connect to a home stereo I have a loud hum (like feedback) when the blue tooth is on and the music sounds very flat and dull. When I change sources I do not have this problem, any ideas?

I had the same problem but solved it by scrapping the provided cable and using my own RCA cables -- red/white tip on both ends, not like the mini-stereo plug provided.

Check that your signal cords are pushed all the way in as far as they will go. Then power off and back on if necessary.

Sounds like a bad connection to me.. Be sure to push the cable connecter ends in all the way into both devices. If you still are experiencing the hum. Try a different patch cable altogether. If still has hum! Check the connection on you stereo component with another input device. Ipod, MP3, Or even a CD player. That is if you have one! If the hum goes away . Throw away the bad cable. Should there still be a hum! It is possible your adapter may be faulty, Or your receiver or Stereo amplifier might have a bad filter, or your are picking up an interference from a local source. I would suggest you return the logictech adapter and try to exchange it. Before condemning Your equipment. Just as a suggestion oc course!
Hope this helps! Good Luck!

Do not plug this into the phonograph input. Use auxiliary or cd

You might try plugging it into a different input on your home stereo. The impedance or resistance is different for different types of inputs so it may sound good on auxiliary but not on phono or vice versa. Just a suggestion.

sounds like a ground loop. Is something touching the RCA or headphone cables? Are the audio cables running parallel to a power cable? You might have a bad power supply on the Logitech device, as it shouldn't produce any sounds on its own.

Check your cable connections and make sure they are all tight. If that doest work, try changing the connection to the Bluetooth to your speakers from RCA to audio jack or vice versa

Sounds like you are plugging it into phono input or some other that isn't matched. Not sure what your other sources are. Perhaps the one that doesn't work is damaged but only way to tell is get another.
