Hello,
about a week ago my Logitech P5800 speakers started doing weird crackling/popping sounds when listening to youtube, also sometimes audio speeds up and slows down. I am definitely sure that the problem is not with my speakers, because when I listen through them with my phone I don't hear the weird sounds. Also, the popping sounds appear not only on youtube, but when using winamp, vlc, gaming and so on... I have tried to disable all sound enchantments and lower the sound quality to 16 bit 44100 Hz but it is still going on. Can you help me to sort out this issue? P.S. when I listen through USB headphones I don't hear the weird sounds.
