Hello.
I've had a Raspberry Pi 2 for a few days. It is connected to the TV with HD MI, but I want to use audio system in analog output. I configure audio in O penELEC in analog mode. But, when I play music or watch a video, there is a quite annoying background noise, as interference, which only attenuates if I turn the volume up.
It isn't a speaker problem because I've got the same problem with the headp hones. The noise or interference it's only heard when the speakers are emit ting a sound. In fact, the sound of the menu also has interference. The HDM I sound is fine , but I'm interested in analog output.
I've been looking for a solution for a couple or days, but I haven't found a solution. I've even tried to install a ferrite filter in the power cord , but it hasn't worked.
Have you got any idea of which could be the problem? Thank you very much.
