Speaker malfunction / diagnosis

Hello,
my speaker is acting up and more or less stopped working.
Is there a way to check whether its a software or hardware related problem before ordering replacement parts?

There are some basic diagnostics, yes, but having a better idea of exactly what you are experiencing and when/how would help guide you further.

Can you share further details about exactly what is going on, how and when you experience it, and what you have tried thus far?
