Missing advanced audio settings

[sbeaupre]

Hello, 

When I use Zoom and play guitar (electric), the sound is muffled. 

When I click on settings > audio > advanced, I only see "echo cancellation" as an option. There are no settings for "background noise suppression." My understanding is Zoom detects guitar as background noise and suppresses it, so I need to turn off suppression. However, the option does not appear. I am using the latest version of Zoom w/ Sonoma 14.6.1 on my Macbook. I have a Zoom Workplace Basic account. My microphone is working properly. Interestingly, there are audio options for "original sound for musicians" and "Live performance audio"  but those selecting either of those options has no effect. The guitar is still inaudible/muffled. 

Zoom help articles don't seem to help: 

This article only refers to echo cancellation when describing advanced audio settings. 

This article also refers to noise suppression.  

Thanks, 

Steve
