PocketGo no longer outputting sound

[ZXT-92]

My PocketGo (which I've had for a good long time now) won't output sound anymore unless it feels like it. Pressing Select + Y or B does nothing. However, one time when I removed the Micro SD Card while the system was on, the sound came on, then when I put the card back in, it turned off.

Any help would be appreciated. I'm using a 32GB Micro SD Card, not the 8GB one that came with the system.

EDIT: It's a PocketGo v1.

Never Mind. I found out what the problem was: The Micro SD Card slot was dirty. Once I cleaned it, the sound played perfectly again.
