Changed the computer and changed the sound can you help?

Hi, I changed the computer and installed audacity again in the new computer, I’m not an expert so I’ve problems to understand what changed when I record my voice sound less clear, I attach an example, before and after, what can it be? can you help?

It sounds like a case of Windows audio enhancements, (e.g. echo cancellation),
which are on by default and should be switched off for a faithful recording.

You should disable all “enhancements” for your microphone in the recording tab of Windows sound …

It worked, thank you so much!
