Hey there!
My name is Ravi, an independent advisor and expert user. I am happy to help you. :)
I understand how uncomfortable it can be to have such a muffled audio.
Could you please try this solution?
>> Go to your audio and input settings and make sure your input is not your headphones but anything else like a PC mic.
Feel free to get in touch again if you have any additional questions.
Cheers,
Ravi
