My right front speaker in my 5.1 home theatre setup has recently started crackling whenever I turn the volume up or a loud sound comes through it. I've tried swapping the speaker with the left one and same issue so it's not the speaker itself. I also pulled out all the speaker connections from my AVR, checked the ends and put them all back in making sure the connections are all sound so it's not that either. That seems to only leave the AVR itself I guess. A bit of googling suggests that the front right channel may be knackered. I tried resetting all the speaker settings and set up the surround again but it's still doing it. What can I do from here? Is it likely the AVR channel is actually poked? If so, is there anything I can do about it myself? Anything else left to rule out? I recently changed my front speakers to bigger more powerful floor standers but the crackling didn't start straight away. Haven't been thrashing them either, just started doing it a couple weeks ago. Cheers
