Can't stop noise suppression on HP laptop

In one of the Zoom meetings I run, I use a meditation bell. On my other computers, the sound is clearly heard by participants if I turn Zoom noise suppression to low or use the original sound setting. On my new HP Laptop 17, it is suppressed regardless of Zoom settings, including when "original audio" is turned on. The suppression occurs whether I use the internal microphone or the one on my Logitech webcam.

I found and turned off noise suppression in the "HP audio center" app, but the meditation bell is still being filtered out. I've also disabled enhancements in the sound card. 

HP support had no suggestion other than to try their for-a-fee support team.

Any suggestions welcome, as this is an essential part of this meeting.
