J-Tech Digital Premium Quality 1080P HDMI to HDMI + Audio (SPDIF + RCA Stereo) Audio Extractor Converter (JTDAT5CH)
This device extracts the digital audio signal from the HDMI input and converts it to 2 channel analog stereo output or 5.1 channel Audio outputs.
To improve our customers experience, we posted the following three methods if you experience no sound from output.
1. Switch EDID Button
Switch the EDID audio switch in the front. Change it between 2CH, 5CH or pass.
2. Turn Off Dolby Digital Plus
Because TOSLINK (SPDIF) does not support Dolby Digital Plus, you need to turn off Dolby Digital Plus function of the input devices. Then the sound can go through the extractor.
a: Amazon Fire TV or Amazon Fire TV Stick
Settings - Display Sound - Audio - Dolby Digital Output - Dolby Digital Plus off
b: Apple TV

Chromecast plays the contents from your video source, please make sure to turn off the Dolby Digital Plus on the video source through the play devices.
3: If you use the HDMI to DVI or HDMI to VGA cable for the video, you may experience no audio out. In this case, please use HDMI to HDMI cable for the video.
