Audio input and routing

Great translation depends on a clean speech signal from your sound desk. These steps help you, your tech team, and volunteers resolve the most common audio input problems on Sunday morning.

For general setup guidance, see Audio input.

Breeze is using the wrong audio input

Symptom: Breeze is running, but it picks up room chatter, coughing, or ambient echo instead of the clean sermon feed from your sound desk.

Cause: Web browsers often default to your computer’s built-in microphone (webcam or laptop mic) if the primary audio interface is not explicitly selected or permitted.

Steps:

1. Check browser permissions. Look at the address bar in your browser. Ensure the microphone icon does not have a red line or blocked symbol. Click it to allow microphone access.
2. Explicitly select your input. On the Broadcast page, open the Settings card and use the Audio Device dropdown. Select your USB audio interface or line-in option directly — do not leave it on the default device.
3. Test the browser connection. If the device is not showing up in Breeze, try testing your audio input using our simple recorder to see whether your browser can detect the hardware at all.
4. Close other software. Make sure other open programs (Zoom, Teams, or OBS) are not locking your audio device for exclusive use. This is more common on computers running Windows.

Digital desk connected via USB but Breeze receives silence

Symptom: Your digital mixing desk (Allen & Heath SQ series, Behringer X32, Yamaha TF, and similar) is connected to the computer via USB. The board shows signal, but the audio level bar in Breeze does not move.

Cause: Web browsers (and progressive web apps like Breeze) can only listen to USB channels 1 and 2 of an incoming multi-channel USB stream. If your sermon mic or main mix is assigned to channel 3, 4, or higher, the browser receives silence.

Steps:

Method A: Route your sermon mix to USB 1 and 2

Go into your mixing desk’s routing or patching grid. Assign your sermon or pastor mic — or a dedicated Breeze aux mix — directly to USB outputs 1 and 2 (sometimes labelled Card Out 1 & 2).

Note: On some digital desks, or some church setups, USB outputs 1 and 2 are pre-configured or reserved for other system feeds. If you cannot change this, proceed to Method B or C.

Method B: Use virtual routing software

If you cannot reconfigure your desk’s USB outputs because they are locked for multitrack recording or live streaming, use software to grab your sermon channel and send it to virtual channels 1 and 2.

• macOS: Use Rogue Amoeba’s Loopback or the free utility BlackHole. Create a virtual device that takes input from channels 3/4 (or whichever channels carry your sermon) and maps them to virtual output 1/2. Select this virtual device as your Audio Device in the control panel.
• Windows: Use VB-Audio Voicemeeter or Voicemeeter Banana. Set your hardware input to your digital desk’s ASIO driver, then route your sermon strip to the Virtual B1 (VAIO) output, which Breeze can read as a standard two-channel microphone.

Method C: The analog fail-safe

If digital routing is too complex, take a spare analog output (aux send or matrix out) from your desk and run it directly into your computer’s analog line-in or microphone jack, or a simple audio interface. This bypasses multi-channel USB routing issues entirely.
