Is laptop sound automatically quieter?

I have a laotope that also does a good job. For a few days, dmes is now so that the volume on spotify, netflix and everything else is automatically reduced, so it is 3 seconds on the usual volume and then it becomes so quiet that you have cellphone volume, so to speak, what can it be?

It's up to the speaker

You are chewing for a short time, why don't you keep it easy?

Because volume was turned down

From whom not from me

Alexa or siri

I don't have both

I'm sorry, I don't know what to do next, just ask google

I did the last 2 rounds and found nothing…

Yes, maybe change the browser for better results
