Just curious, did a quick teardown just to see the innards. I put the controller back together and everything is good except for one thing, which isn’t a deal breaker just a little annoying, the light on the mute button. The actual mute button works, as I have it mapped for my toggle mute on discord, but for whatever reason the light won’t go on, any help on this? And if I need replacement parts can someone point me in the right direction? Thank you in advance!
Remove the controller case, see if the LED actually lights up. If it lights up, probably the button wasn’t assembled correctly and the rubber cover got wrinkled up, blocked the light.
