KEF LSX II User Manual page 89

• If there is only no sound but everything else is working, please make sure that the
audio output of HDMI is set to PCM (this is often set to Dolby Digital by default).
As the settings menu of each TV manufacturer is different, please refer to the user
manual of your TV. Also check the settings within the application in use (e.g. Netflix
and Disney+) and make sure PCM is selected.
• Change the HDMI cable (our internal tests found that HDMI cables of lower quality
may not be able to establish the connection) and make sure the HDMI cable is
properly connected.
• As a last resort, power cycle the TV (unplug the power cable from the TV and wait
about 10-15 seconds before plugging it back in) and try again. Smart TVs are like
phones and sometimes require a reboot.
• If the problem persists, please report the issue in the Support section of the KEF
Connect App for investigation. In the meantime, use the Optical connection as a
fall-back solution.
10. I have connected the speakers to the TV with an optical cable, why is there no
sound?
• Make sure your TV is set to output digital audio in PCM format.
• If the problem persists, try a different optical cable or connection option (e.g. HDMI).
11. I cannot find a radio station or podcast in the KEF Connect App.
• We are constantly updating and expanding our database for radio stations and
podcasts. Please use the Support function in the KEF Connect App and send us the
RSS link of the website. After verification, we will add it to our database.
12. I cannot adjust the speaker volume.
• Check if you have set a maximum level for volume adjustment.
• Check if you are connecting and controlling the correct set of speakers in the
network.
