Review on Neoteck 4K 60Hz HDMI 2.0 Audio Extractor: YUV 4:4:4, HDR, HDMI to HDMI + Optical 🔌 Toslink SPDIF + Analog RCA L/R + 3.5mm - Perfect for Gaming, PS4 Pro, Blu-ray Player, HDTV by Kevin Greer

This is a 5 star choice for transmitting composite audio output from an HDMI source (BluRay or Roku Satellite DVR/Streamer) when transmitting an HDMI signal to an AVR/4K -TV. Note that many 4K sources only carry DTS MAster Audio or Bitstream for digital audio, not PCM. Bitstream audio sends a standard Dolby Digital or DTS 5.1 surround sound signal (or higher, e.g. DTS Master Audio) to your receiver for further decoding, the PCM option only sends a two-channel signal. to select the PCM audio output option in the HDMI source (Roku/BluRay player) to get a signal that this audio extractor can handle. Otherwise, you will only hear digital noise (hiss) through the analog audio RCA connectors. That means downsampling your source audio to Dolby Pro-Logic versus Dolby Digital+ (anything above 5.1 surround sound) to share over the analog audio jacks.
