M1 Mini Clicking Noise

I’ve had my M1 mini for a week now and it has been running great. So much faster than my old Macbook Pro. I plugged a set of external speakers into the headset port this morning. They work fine but now there is a “clicking” sound (sounds like a spinning hard drive) coming from the mini. It’s still there if I unplug the speakers. I’m not sure if it started right after I plugged the speakers in or after I opened Music for the first time to test the speakers. I saw this article and wonder if it might be the same issue. Anyone else had this issue?

Thanks for the assistance.

Best Regards,

Chris
