Sound is not heard from all speakers

If you're listening to audio on your product but cannot hear sound from all of the speakers, try the following:

Be sure the system is set up properly and all connections are secure.

A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.

If using the Bose B2 bass module, be sure the power stand firmware is version 1.4 or greater.

For the Bass Level switch on the back of the B2 to work with the L1 model II, the power stand firmware must be version 1.4 or greater. If it's not, the B2 will only work when the Bass Level switch is in the Normal position. The + or – switch positions only work if the power stand firmware is version 1.4 or greater. For more info, see Checking the software or firmware version and Updating the software or firmware of your product.

Note: L1 model II systems with a DOM (date-of-manufacture) of 2285 (12 Oct 2012) will work with the B2 without updating.

Check the condition of the L1 connectors, and the L1 connection in the power stand.
