Question

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.

I stated "I select the Yamaha input device as the Zoom microphone", i.e. I select the Yamaha device directly in Zoom, not going through OBS. I only tried it in OBS just as a test comparison to ensure that the Yamaha is actually feeding stereo to the computer. Sorry if that wasn't clear and I wasn't sure what you mean by a diagram, hence I described in words.

OK I read your mixer manual - try the following:

Plug in one mic only to channel 2

Be sure nothing else is plugged in - no speakers, aux inputs, etc.

Plugin your Beyerdynamic headphones into the headphone jack on the mixer (18 in the manual)

set channel 2 gains so you can hear the mic

Which ear do you hear the mic in - L, R, or both?

from the manual

Input Channels Mono (MIC/LINE): 2 (this may be your issue - if it is there may be ways to compensate)

Audio has so many hardware and software buttons, balance controls, driver selections, etc. it becomes very difficult to diagnose without seeing actual settings and actions. If you still feel that the issue is unresolved you may want to arrange a one-on-one zoom meeting via private message so I can help you find what is missing from your story, since there are a lot of possibilities.

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)"
