xbox one s sound barely audible on some controllers but not all of them

Hi YvesBergeron3! My name is Ricardo an independent advisor ready to help you with this situation!

Could you tell me what are those solutions that you have tried? Among these options is checking the volume bar as well as the chat mixer?

First and if you haven't gone through these steps, follow what's mentioned in this link => Troubleshoot your Xbox Wireless Controller | Xbox Support. If that doesn't resolve the issue, you will have to get the controllers replaced by following what's mentioned here => Request an Xbox controller replacement | Xbox Support.

It's the white one, Jasper, as far as I know. The interesting thing is that there is no checkerboard screen and the crackle is (barely) audible only with some games, for instance Red Dead Redemption and L.A. Noire (playing regular DVDs shows no audible crackling
at all). It could be that the games themselves are faulty and that nothing's wrong with the console, which I hope to God is the case since Xboxes are way to expensive here in Croatia.

try disconnecting your audio equipment .. and use the TV speakers.... and nothing else... bare bone it from scratch and add a piece back step by step until the problem starts again... isolate what causes it... sounds like it is picking up a signal or something...
and doesnt really need to be an audible one at that....

no, but i don't often get messages and when i do i delete them as soon as i've read and/or responded to them. my audio is also usually barely audible when i play games lately...
