| Cannot send stereo in Zoom using Source-Nexus I/O | Read through this article to learn how to send stereo audio into Zoom using Source-Nexus I/O. |
| Clicks in the audio | If you are hearing clicking when using Source-Nexus I/O, the problem might be related to clocking issues (see below "Clocking issues" section). Clocking issues are caused by sample rate conflicts. Make sure that your hardware devices have the same sample rate (this applies to any devices, including webcams, that you have connected while you are using Source-Connect). If you are a Mac user, check the Audio MIDI Setup to make sure all devices are set to the same sample rate your session has. Also, make sure the audio device input and output are not muted on the Audio MIDI Setup. If you are on Windows, go to Sounds > Recording/Playback > Device > Advanced instead. If the above does not solve the issue, try creating new drivers and using them instead of the default ones (Source-Nexus A and Source-Nexus B). Check out this article for Mac and this article for Windows. If you are on macOS Monterey or higher, make sure your issue is not related to Apple's CoreAudio problems. |
