Hello there new to the forums, Recently started having some problems with the speakers on my R1. The audio started sounding like some speakers and bass was missing. Checking the levels on my playback devices, seems that the only one working now is the front speakers. (which when turned all the ways down turns the audio off). As the music plays, the bass and back speakers will fade in and cut out from time to time, while the front continues to play. When i plug it into external speakers it sounds fine as far as i can tell, but then again it sounds fine coming out of just the front speakers.. Would this problem be hardware related or is there some configuration/driver that could be causing this. Thanks.
