[BUG] Zoom crashes if the microphone frequency is high

[furtadopires]

Tested version: 6.3.5 (54827)

Trying to open the audio settings or making a call with a microphone configure with a high frequency makes the window crash instantly.

Mic configuration: 1 channel, 24 bits, 192000 Hz

To reproduce:

- Change the microphone settings to 1 channel, 24 bits, 192000 Hz in the windows sound config

- Try to either make a call or open the settings in the audio session

- The call / settings window will instantly crash

Workaround

- Set the microphone to use a lower frequency (like 96000 Hz or lower)

Thanks for this comment I will pass it on

I'm having similar issue. This issue started to appear after I updated Zoom to v3.6.5. My mic has only one input format in Windows settings: 1 channel, 24 bit, 192k Hz.

Several tips I have tried:

1. Uninstall Zoom using ZoomClean and then reinstalling the latest version, does not work❌

2. Downgrade Zoom to older version, does not work, Zoom require latest version to login❌

3. Change input device format/freq, my mic does not have another format available in Windows settings❌

4. Send report through Settings > Statistics > Send Report

For now, I have to switch to other video conference solution while waiting for this issue to be resolved.

Exactly same here!

Not having this issue in MS-Teams nor Google Meet; only happens in Zoom.

I hope a solution by Zoom.  This kind of devices were working fine some releases behind.

I am running into this issue as well.

Same problem, no options other than use lesser microphone.  Please fix as soon as possible.

As an audio engineer what you are making reference to is the digital clock sample rate. In digital audio systems there is a master clock that all other devices are slave to and must be syncd and locked in order for audio to be heard. Typically the master clock is the internal clock on the internal sound card or the clock of an external audio interface. For video streaming the standard clock sample rate is 48KHz. Trying to send audio at higher sample rates would reguire the hardware or software to convert back to 48KHz for streaming. There is no advantage to setting a higher sample rate. 192KHz is only used in audio studio recording situations for tracking to minimize digital artifacts when mixing. Mixing actually resamples the audio to 44.1KHz for final output. Since you have not stated what microphone is being used it is difficult to give precise instructions with respect to settings. Since you make reference to the Windows settings (not clear which OS is being used) the best I could recommend is to try setting the clock to 48KHz (which should work fine since you stated that a 96KHz clock did work). There is no advantage to using higher clock sample rates, but there are numerous disadvantages.

Thank you for the explanation, is useful to understand how to works it. 👍

However the thing is when you have a mic that only runs at "1 channel, 24 bit, 192kHz (Studio quality)" and there is not more options to change the sample rate in the Windows sound settings for it.  There are a lot of condenser mics that only runs at this sample rate without any option to change it or lower the clock setting.

Additionally that mic was always working fine on previous/older Zoom versions.  I've tested on three Windows 11 computers with 32 and 64 bits version of Zoom client with same results.

However, the mic is working fine in other conferencing scenarios:

• Zoom web version
• MS-Teams (client and web)
• Google Meet

Thanks for the reply!

I agree with your statement since I also happen to work with DSP although for AI/ML research. Unfortunately, I can't change the sampling rate (my mic is a generic USB mic: SOUNTEC brand). It is not supported anywhere I know of.  I have checked:

1. Control Panel > Sounds > Recording > Microphone > Advanced > Default format (non-changeable)
2. Settings > System > Sound > Microphone properties > Format (only one option)

While I agree with the downsides of using too high sampling rate, it is what my mic supports. I can't change it. Also, this problem only occurred after updating zoom, therefore I see this as a regression/bug. Is there another alternative I can do to fix this? Maybe a virtual mic driver or anything? (Also, since we're talking about audio drivers, no, my mic doesn't have a manufacturer-provided driver, just from the default Windows driver).

Mic: Rode NTG-2 or EV RE320 (depends on what I am doing) into Black Lion pre-amp.

Interface: Focusrite Scarlett

Software: Voicemeeter Potato

I use Voicemeeter Potato for all routing on my machine. It's looking at the Focusrite ASIO driver for master clock to sync all other hardware (multiple interfaces and a bunch of Schiit gear for monitoring/listening). I want to run at 192khz because I am doing some studio work. Voicemeeter likes all interfaces to be at the master clock sample rate. Thus, running at 192khz across the board.

I appreciate the input...but in this case it's not relevant.
