Why is there no sound from my Bose LIFESTYLE 600 Home Theater System?

If there's no sound from your Bose Home Theater System, try these steps: First, increase the volume and ensure the system isn't muted by pressing the Mute button on the remote. Verify that you've selected the correct source and try cycling through different sources. Check that the HDMI cable is properly connected to the ARC (Audio Return Channel) connector on your TV. If your TV lacks an HDMI ARC connector, use a secondary audio cable along with the HDMI cable, inserting it into the Output or OUT connector on your TV. As a last resort, unplug the power cord for the console, wait 30 seconds, and then firmly plug it back into a live AC outlet.
