Sound is coming

Make sure that the soundbar’s HDMI cable is inserted into a port on
your TV labeled HDMI eARC (Enhanced Audio Return Channel), not
a standard HDMI port. If your TV doesn’t have an HDMI eARC port,
connect to the HDMI ARC port. If your TV doesn’t have an ARC port,
connect to the soundbar using the optical cable (see page 47).
Disconnect the HDMI cable from your TV’s HDMI eARC (or ARC) port
and reconnect it.
Unplug the power cords for the soundbar and optional bass module
or surround speakers, wait 30 seconds, and firmly plug them into the
AC (mains) outlet.
Turn o your TV speakers. Refer to your TV owner’s guide.
Decrease your TV volume to its lowest setting.
If the soundbar is connected to your TV’s HDMI eARC (or ARC) port,
make sure that Consumer Electronics Control (CEC) is enabled in
your TV system menu. Your TV may refer to CEC by a dierent name.
Refer to your TV owner’s guide.
Check the Advanced CEC setting in the Bose8 app. You can
access this option from the Settings menu. For more information,
