Audio Extractor Aigrous 1080P HDMI Audio Extractor HDMI to HDMI + Optical Toslink(SPDIF) + RCA(L/R) Stereo Analog Outputs Video Audio Splitter

One HDMI input converts to one HDMI+ Audio (SPDIF+R/L)output
Aigrous Audio Extractor extracts the digital audio signal from the HDMI input and converts it to 2 channel analog stereo output or 5.1 channel Audio outputs. Supports the highest video resolution to 1080p. Supports 225MHz/ 2.25G bps per channel bandwidth.
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.
