Muffled voice recording through mic on Windows but not Mac


I am recording on my Windows 11 laptop, using a Samson Q2U microphone (USB connection).

I’ve done so many times in the past without issue, but now my recorded voice is muffled and sounds like I’m on the other end of a phone. I wondered if this was an issue with the microphone, but I’ve just tried downloading Audacity on a Mac and recorded voice through the same mic remains perfectly clear!

All the settings remain the same, so the issue appears to be with my laptop. Does anyone have any ideas how I can investigate and hopefully remedy this? Could it be a problem with the USB plug-in point? I’m at a loss to think of what else it might be.
