UPDATE: The issue is fixed in version 26.1 for macOS.

If you have updated your macOS to version 26 Tahoe, we are aware that the microphone in the Huddly IQ w/mic is not showing up as an audio input.

In the meantime, if you use your Huddly IQ as a microphone, we recommend postponing the macOS Tahoe update until the audio issue is fixed.
