Features: Extract audio from HDMI sources to external sound systems via SPDIF Optical (Toslink) and/or RCA (3.5mm) analog output o For simultaneous SPDIF and RCA output, set HDMI source audio to Stereo (PCM). o Note: Not compatible with HDMI-ARC function Supports video resolutions up to 4K@60Hz, 1080P@120Hz, and 1080P@144Hz with HDR 10-bit color o Fully compliant with HDMI 2.0b, HDCP 2.2, and EDID Versions 1.3 & 1.4 3-mode Audio EDID switch for selecting 2CH stereo, 5.1CH multi-channel SPDIF, or pass-through audio formats o Note: Does not downmix digital audio to analog 3.5mm output Supports CEC pass-through for device control and HDMI High Bit Rate (HBR) audio formats via SPDIF Please Note: If you’re not receiving audio from the Optical (SPDIF) or 3.5mm output ports, check your source device’s audio settings: Set audio to PCM for 3.5mm output Set audio to PCM, DTS, or Dolby Digital for Optical output If you HDMI source devices’ audio format is set to Dolby Digital + (or higher), the extractor will not output audio via optical SPDIF or 3.5mm since the highest audio format supported by optical SPDIF is standard Dolby Digital 5.1, and 2CH by 3.5mm analog output

Review: This is one of the few solutions to be able to extract Audio from an HDMI signal to an Optical Output (TOSLINK) AND also have the audio going to the HDMI output.
Review: It took a little research on how to set it up right in order to get 5.1 audio from the optical cable. Many mention setting to PCM on the Firestick, but optical doesn't have the adequate throughput for 5.1 channels. Dolby digital+ would be ideal, but Dolby Digital setting worked for me. This is basically a budget home theater setup using an Elephas 4k supported projector, which does look much better in compressed 4k than standard 1080p, so the HDCP support helps to get the 4k picture. No noticeable audio lag. Connectivity was simple.

*by E***N on 13 August 2025*

High quality sound with no latency. I’m using this box to go from a streaming device to this box which splits out the sound to my balanced sound input connection and using studio monitors for sound output. The quality is super crisp. Would recommend. Good value for what you get and small enough to pop it behind any crevice you can find.
