Hello, I also have a problem after loading v250905, I have a strange sound when playing mp3 music in the speakers, as if I were pressing the phone buttons to call, there are about 6 signals on each song, and also in the sub woofer there is a big popping sound when one song ends and the next one starts, it looks like the amplifier is turning off and on for a moment, I checked the connection and remote system power to the amplifier and it is correct, any advice?
