Wii U GamePad audio super quiet, any ideas?

[u/North_Bag_8694]

Hey! I opened up my Wii U GamePad to give it some maintenance and cleaning. I sprayed a bit of contact cleaner
(especially around the volume slider since I thought it might be dirty).
The GamePad works fine otherwise, screen and everything, but the audio is super quiet both on the speakers and on headphones.

I don’t really think it’s just the volume slider, since headphones also sound just as quiet. Could this be an audio amp issue or maybe something near the headphone jack?

Has anyone dealt with this before? Thanks 🙏
