Zoom Audio not picking up the Music instruments sound even after enabling the original sound

[KrishanK]

Zoom Audio not picking up the music intrumemts sound even after enabling the original sound for musiciation. I am having this issue for the last six months, hoping Zoom would iron this out. However, it has been working previously.

I have tried all the zoom settings. No luck.

I have also checked Mac, as to whether it is dropping the input. But, Mac is taking the instructions sound.

I have tried with a professional audio card, and it is confirmed Zoom is dropping the music instrument sound. 

Zoom Team: I would appreciate it if you could address this issue. 

Note: I am not a paid user currently, but my tuition provider has the paid version. 

Zoom version: version 6.4.0 (51205)

OS: Moc OS (Apple Zip) - 15.3.2 (24D81)
