Cannot seem to configure audio for music lessons

[Ash2024]

I have been struggling to figure out why my guitar cannot be clearly heard on music lessons via Zoom. I have set the audio according the the suggestions of my teacher and also what zoom recommends and still my guitar sound is cut short. 
Advanced settings are as follows:

1) original sound for musicians checked 

2)high fidelity mode checked 

3) echo cancellation not checked

4) stereo audio checked 

if I check zoom background noise removal then original sounds for musicians becomes unchecked.

does anyone have any suggestions?

You were fine up to step 3. The setting in the meeting is still off by default so you still must turn on the setting in the meeting in the upper right of the Zoom window. Click "Original Sound for musicians" so it goes from off to on.
