In the TV menu, look for applicable audio/sound settings.
Many TVs have a menu setting that allows audio to be sent to speakers other than the TV speakers. In the TV menu, navigate to sound settings and look for a TV Speakers or Audio Output option (or something similar). The TV speakers may need to be turned off and the output may need to be set to Fixed or External Speakers. (Tip: If there is no fixed output option, you might need to turn up the TV volume to max to hear it through your Bose speakers—even if the TV speakers are turned off.)
Check the volume level on the Bose system.
It is possible the volume is too low or muted. Increase the volume gradually.
Check that that the correct audio input source is selected.
If multiple audio sources are available or connected, be sure the correct source is selected. For example, if the audio device you want to hear is connected to the an input labelled AUX, be sure that AUX input selected.
Check that that the correct audio source is selected.
Since there is more than one audio source built-in to your system (i.e. FM and AM radio), be sure the source you want to hear is selected on the system.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
If your bass module was replaced with another unit, determine if it has a dual-voltage switch.
A dual-voltage bass module will have a red switch near the power jack indicating whether it is set to operate on 115 or 230 Volts. If your bass module has a dual-voltage switch, be sure the correct voltage setting is shown. If you need to change the switch setting, unplug the bass module power cord, change the setting, then reconnect the power cord.
Connect the 1/8-inch plug of the audio input cable into the System Control 2 jack.
It is possible that the System Control 1 connection is bad. The System Control connections sends on/off and volume commands to the Acoustimass module. If one System Control connection works and the other does not, determine the Warranty or Rapid Response status and explain Service Options for the media center.
Be sure nothing is connected to the headphone jack.
The speakers are automatically muted when headphones (or any cable with an 1/8-inch stereo plug) are connected to the system.
Check the condition of the speaker wires and be sure they are secure at both ends.
Check the speaker wires for any kinks, scratches, cuts or damage. Replace any damaged wires and check that they are securely connected at both ends.
Try another input on the Bose system.
The input may be defective; try another input (it is ok to use a different type of input, for example analog instead of digital or digital coax instead of digital optical). If the problem only occurs on one input, that input may be defective. Follow the link below for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.
