If Xeo has been connected to the headphone output, please check whether the output must first be activated via the television menu.
If Xeo has been connected via the optical-digital output (Xeo 2, Xeo Transmitter) or coaxial digital (Hub / Connect), check in the television menu whether the optical / coaxial output emits a PCM stereo signal with maximum 16 bit / 48 kHz. Surround signals or up-sampled signals cannot be decoded by Xeo.
