Zoom bluetooth audio crippled

Hi,

 

I have this issue where during a Zoom meeting, the audio suddenly starts to sound crippled. On a level that I can barely understand what others in the meeting are saying. This only happens when I use a bluetooth headset. At first I thought the headset was the issue. I got it replaced by a headset from a different brand, but the issue remains. I don't have crippled sound when using the headset for e.g. listening to music. It also does not happen always. I can get the sound back to normal by disconnecting the bluetooth and then connect again. I hear from colleagues that they experience the same with different headsets and also only with Zoom.

 

Does anyone else recognize this problem? Is there a way to prevent the crippling from starting? It's really annoying to have to disconnect the headset in the middle of a meeting!

Audio is very complex on computer systems and depends upon many factors. You have not stated what device and OS is being used which further complicates the possibilities.

As a best guess I would guess that you did not connect to the device using the bluetooth connect feature of Zoom.

Hi @storyhub ,

Thanks for your reply. I run Zoom on a MacBook air (M2, 2023) running macOS 15.1. I've updated to the latest version of Zoom.

Can you elaborate more about the bluetooth connect feature? As far as I'm aware the bluetooth connection is the responsibility of macOS. But let me know if there's another way to connect, happy to try!

Apple devices are very complicated when it comes to audio because Apple wants to try to control everything without giving the user much choice. Apple is very picky about integrating hardware it does not sell.

First be sure you have installed the CORRECT version of Zoom "for apple silicon". If you installed the Intel version it will not work with the headset.

Uninstall Zoom then follow:

Make sure that the Sony headset has been CONFIGURED as I mentioned earlier. If it is configured for music that is the WRONG setting.

Be sure that the headset is connected in Zoom's audio settings.

Be sure that all OS permissions are set for using that audio device.

Be sure that the OS audio is set to the bluetooth headset.

You may also want to try the headset on other Apple devices such as iPad or iPhone to see if it works with those devices. Be sure that all other devices have bluetooth turned off or disconnected from this device.

Thanks for you reply, @storyhub !

Can you elaborate more on the "Bluetooth Connect" feature you mentioned? As far as I'm aware, the only way to connect a bluetooth device is through the macOS bluetooth menu.

Apple devices have very complex audio management requiring permissions and special devices that follow all of Apple's requirements. If the device connected only supports 44.1K sample rate that can lead to issues. If the device connected is a bluetooth speaker and a mic that device may not work as a speaker device for shared audio because it is a bluetooth device. Bluetooth is not a well established standard and is not a recommended technology in the pro audio world because of many incompatibility situations. If your bluetooth headset was not produced by Apple then incompatibility is an expected issue. Additionally, bluetooth has significant latency that will throw lip sync off. As an audio engineer we avoid bluetooth devices because of all these issues. On iPads and iPhones Zoom has a separate bluetooth connect function as a part of the speaker function. A bluetooth device that works on an iPad or iPhone with Zoom may not work on a PC with Zoom even when it APPEARS to be properly connected. If you want to use Apple devices and their airplay technology it is highly recommended that you ONLY use Apple bluetooth devices. Apple does not give out all the compatibility rules to other manufacturers to force users to use only Apple devices. If you want to use non Apple devices it is best to use USB or analog technology.

    Your diagnostic logic is flawed. The issue is not with the Zoom software, since there ARE numerous bluetooth devices that DO work with Zoom and IOS and ARM processors. The issue is with the design of the hardware you are using. This I do know as an electrical engineer that designs audio/video systems. Your specific selection of hardware (which you have not yet identified) is the most likely issue. What you SEE is people using bluetooth hardware to do what that hardware was specifically designed to do. This does not mean that the bluetooth technology is not without ambiguity , limitations, or subject to special uses. The medical industry uses a form of bluetooth that is used in pacemakers that does not require pairing yet it is very secure. There are different versions of bluetooth that are not compatible with certain hardware. Bluetooth has lots of compatibility issues. Some of these issues are recognized in the following article

    Here is a partial list of Zoom certified hardware, but it does not guarantee that the hardware will work with your hardware.

    I'm having similar issues that *do* indicate this is a Zoom problem.

     
    If I am sharing music on zoom using the "sound for musicians" settings while having the speaker AND the mic set to the earbuds, the audio sounds terrible, with dropouts on the lows, only highs coming through, lots of distortion.
    If I then select a different mic while keeping the earbuds as the speakers, the audio becomes clear and high quality, but the right earbud cuts out (which happens to be the earbud with the mic).
     
    I don't experience this issue on regular Zoom calls (without music).

    I am using SoundCore Space A40 bluetooth earbuds, but I am experiencing something similar with my Sony over-ear bluetooth headphones.
