C8. The audio is out of sync with the picture when using LS50 Wireless II with a TV.
If available, try the video delay/lip sync function of your TV.
C9. I have connected the speakers to the TV with an HDMI cable, why is there no sound?
Make sure the source is switched to TV for the speakers. Check the TV icon on the top panel of the Primary Speaker.
If the TV icon is blinking, the HDMI connection is not found. In this case, make sure that the HDMI cable is connected to the eARC or ARC port of the TV.
If the TV icon is pulsing (fade in/fade out), only CEC (not ARC) connection is established (TV may respond without sound). In this case, do the following:
The HDMI CEC connection needs to be enabled on the TV. As manufacturers may name this connection differently (e.g. Anynet+ for Samsung, Simplink for LG), please check the user manual of your TV on how to turn on HDMI connection for your TV. Once the HDMI CEC connection is enabled, the TV icon on the top panel should turn solid (both CEC and ARC connections are now established).
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.
For HDMI eARC input, make sure the connecting HDMI cable is of high speed with Ethernet to provide sufficient bandwidth and speed.
Change the HDMI cable (our internal tests found that HDMI cables of lower quality may not be able to establish the connection).
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.
C10.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.
C11.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.
