🔇 No Audio / Very Quiet Audio

Solution:

• Check that your USB adapter is firmly connected (see compatible adapters)
• Increase the Input Gain slider (especially for Sonos adapter)
• Verify your Bluetooth headphones are paired and connected
• Check the IFE system volume (it should be at a reasonable level)
• Try unplugging and reconnecting the USB adapter

🎧 Bluetooth Headphones Not Selected

Important: Bluetooth headphone selection is controlled through your iPhone or iPad's system settings, NOT through the IFE Bridge app.

Solution:

• Open your device's Settings → Bluetooth and select your headphones from the list
• If you still have no audio, tap the Advanced menu icon (top right corner of IFE Bridge)
• Check the Audio Output Selection - does it show your Bluetooth headphones?
• If it shows a different device (like iPhone speaker or another audio device), go back to Settings → Bluetooth on your phone or iPad and select your headphones
• Remember: You cannot change audio output from within the IFE Bridge app - it must be done through your device's Bluetooth settings

⚠️ USB Input Not Detected

Solution:

• Unplug and replug the adapter
• Try a different USB-C to 3.5mm adapter
• Restart your device with the adapter connected
• Check that your adapter supports audio input (not all adapters do)
• Try cleaning the USB-C or Lightning port on your device

📶 Audio Stuttering / Dropouts

Solution:

• Increase buffer size in Advanced Settings (Settings icon → Advanced)
• Ensure your Bluetooth headphones are charged
• Keep your device close to your headphones (within 3 feet)
• Close other apps that might be using audio
• Restart both your device and Bluetooth headphones

🔊 Crackling / Distortion

Solution:

• Check if the Input Level meter is hitting 100% (clipping)
• Lower the Input Gain slider if clipping
• Try a different Bluetooth mode (A2DP recommended)
• Reduce the IFE system volume
• Check that your USB adapter is not damaged
