Cannot get stereo audio no matter what

I've enabled original sound for musicians (and yes, clicked the button at the top to actually turn it on), enabled Stereo in the audio settings. Even went to my account settings to enable and force stereo audio for clients. I've recorded the meeting onto the computer. And sound is mixed down to mono... The music I'm playing is stereo, the microphone device is sending stereo, but Zoom is outputting and recording a mixed down to mono version which sounds hollow because the L and R channels of the source are out of phase and when they're simply added they cancel each other out. How do I get Zoom to actually record and send stereo audio?

Which audio device (please include both hardware and driver details + OS info) is being used as the desired stereo microphone/input?

Is this the only source of stereo audio, or is stereo audio also coming in via content-sharing, far-end participants, etc?

This info will help to inform next steps for troubleshooting.

Thank you for replying. I'm running Windows 11 and the microphone device is Yamaha AG06 USB audio mixer. This is the only source

Unfortunately, I can see that Zoom does NOT RECORD STEREO for local or cloud for either the mic or the screen shared audio. The recorded audio is a mono m4a file. The stereo selections are only for the streamed audio during the meeting. However, there is a work around. You will need to install OBS Studio and NDI. You can route your audio (and your video) thru OBS Studio, output the audio (and video) using NDI. Zoom supports NDI and it can be selected in the audio and video settings. Then make 2 separate recordings using OBS Studio and Zoom. Then combine and sync the 2 in a non-linear editing application such as Premiere Pro. Although this sounds a bit complicated it is doable.

Hi and thank you for this. However what I'm observing is that I'm not getting stereo audio even during the meeting. I have my headphones plugged into my phone in order to check and the sound is still mono (the two channels merged together and played through both sides). I can tell because there's a huge difference in how it sounds due to the phase cancellation I mentioned.

Hi and thank you for trying to help, really appreciate it. However the issue I'm having is with stereo music played via an mp3 player connected to the stereo Line inputs on the mixer. The music fed into the mixer and coming out of the mixer is definitely stereo (I've confirmed that). The audio file played is such that L and R are different and out of phase so that if you merge the two channels they partially cancel each other out. I'm hearing this cancellation in Zoom, but not anywhere else (not OBS, not my headphone, not my speakers).

Ok, that is new info I didn't have before. However, if you would still like one-on-one assistance it is available. Just let me know. Did you try connecting OBS Studio to Zoom using NDI or the virtual camera or a third party virtual cable?

when you are sharing the screen, and selecting "share sound" there is dropdown menu there that you can change the default mono audio to "Stereo (high fidelity)"
