No audio from product

If your product seems to be set up properly but does not produce sound, try the following:

Be sure there is no active phone call.

For clear communication when on a phone call or with any incoming Comm, the auxiliary audio is automatically muted. If the call is not ended, aux audio will not return

To end a phone call, briefly press the Bluetooth® function button. Two short beeps should be heard in the headphones to indicate that the call has been ended.

On the control module, try the MIX position

If noise from the intercom or aircraft is loud enough, the headset might recognize it as intercom audio. This will cause auxiliary audio connected to your headset to mute If the switch on the headset control module is in the Mute position. If auxiliary audio does not mute when using the middle MIX position, try adjusting any applicable intercom settings or use MIX and adjust levels so intercom audio is not missed.

If you have ever unplugged the microphone cable from the headset, disconnect it again and check for debris or damage at the connectors.

Make sure the connectors on the cable and at the headset are both free of debris (dirt, lint, dust, etc.) or damage, which could prevent a proper connection. For more info, see Attaching or moving the boom microphone on the headset.

Check the volume setting on the intercom/radio.

Adjust the volume knob on the intercom and/or radio and listen for a change in the volume level.

Check the audio panel settings.

On the audio panel, adjust the squelch setting to match the headset mic level. Open or close the squelch setting while speaking into the mic until the mic signal is clear and consistent. Some audio panels have an Auto-Squelch (VOX) feature which can still be manually adjusted using squelch controls.

Turn up the volume of the connected device.

Set the device volume to 90–100% to send a strong signal to your product. Then, use your product to adjust the volume level.

Check if the headset is connected to your Bluetooth® device.

On your headset control module, the Power and Bluetooth lights blink in sync when your headset is connected to a Bluetooth device. If the Bluetooth light is not blinking in sync with the power light, your headset is ready or trying to connect via Bluetooth. For more info, see Connecting a Bluetooth® device.

On Android devices, check if Phone and Media audio are enabled in the device Bluetooth® settings.

Many Android devices let you turn on or off in-call audio and streaming audio for individual Bluetooth speakers or headsets. This will prevent phone or media sound from playing on a connected Bluetooth product. To check these settings (instructions vary by device):
  1. On the Android device, go to the Bluetooth settings and view the list of available Bluetooth products
  2. Select your Bose headset to view its settings. Typically, this is done by long-pressing the headset name in the list
  3. In the Options menu for the headset, be sure both Phone and Media are checked
If audio still doesn't play, turn your headset off and back on, then try again.

See if the power light is lit on the headset control module.

The LED light on the control module should light when powered on. Press the power button once to turn on the headset, then see if the light is lit. For more info, see Understanding LED indicator status lights and information.

Determine if the 6-pin-to-G/A adapter is being used.

If using the 6-pin-to-G/A adapter cable, check the condition of the cable and its connectors. If the adapter is damaged, replace it.

Determine if the issue occurs with a connected Bluetooth® device.

Be sure the audio mode switch is not in the down (Intercom Only) position. Disconnect the headset from the panel and connect a Bluetooth audio device—like a smartphone—and play some music.
  • If the issue still occurs when playing music from the Bluetooth device, there is an issue with the headset
  • If the issue is not present with the Bluetooth device, the aircraft connections or settings could be the issue

Clear your product's memory of previously paired Bluetooth® devices, then reconnect.

Your product remembers the last several devices it connected to so it can quickly reconnect to them. In case of an issue with the device memory, clear it, then create a new memory by re-pairing your Bluetooth devices. For more info, see Clearing the product memory of paired Bluetooth® devices.

Clear the memory in your product of previously connected Bluetooth® devices.

For more info, see Clearing the product memory of paired Bluetooth® devices. Once cleared, reconnect and try again. For more info, see Connecting a Bluetooth® device.

Plug in a different headset.

If available, connect a different headset to the aircraft to determine if the issue is related to the aircraft panel or its settings.

Connect the headset to a different panel jack or, if possible, to another aircraft.

Non-TSO equipment, worn jacks/loose connections, or incorrectly wired jacks (i.e. reversed stereo or mic / ground wires) in the aircraft can cause issues. If available, try connecting the headset to another jack in the aircraft or to jacks in a separate aircraft. If the headset works fine when connected elsewhere, the panel jack or wiring to the jack is the issue.

Disconnect all other headsets connected to the aircraft.

Unplug any other headsets connected to the aircraft intercom. If the issue goes away, it is related to another headset. Reconnect the headsets one-by-one to determine which, then check the settings for that headset.

Determine if the Multifunction switch clicks twice when moved up from the off position.

If the switch does not click a second time when being moved from the bottom (OFF) position, the top position is not being fully engaged.
