SPDIF output is supported. Make sure that the TV has HDMI "ARC" interface and only supports TV with HDMI ARC function. Before using HDMI ARC, set the audio output to PCM or LPCM. (When the output audio is 3.5mm AUX stereo or L/R RCA, you need to set the output of the audio source to LPCM/PCM format.).
