sound terrible with music

[Irene8]

since I have the paid zoom version the sound is bad especially if someone uses music in a webinar eg mediation and so on it does not reach me. My iphone without the paid accound can do it. my laptop with the paid account cannot do it. and my technicans tell me it is not the probelm of the computer that is working perfectly. any other dieas, nobody could help me not even zoom. thank you
