Review: It works well - I'm normally hesitant to buy this sort small-brand Chinese hardware that floods desertcart, but there were no well known brands offering this part so I gave it a try. Happily I have had no issues. The option to use optical, 3.5mm, or hdmi pass through is very nice. I have not noticed any timing or latency with the audio matching up with the video. I took the enclosure off mine because I will be putting it inside a different system. the board is compact and clean.
Review: Works well with our system - Great sound quality

## Features

- 【Digtal/Analog audio to HDMI embedder inserter】Use external audio from either digital (optical---TOSLINK/SPDIF) or analog (3.5mm/line) sources to replace the audio from an HDMI signal(Note that the original HDMI sound is replaced, not mixed with the original HDMI sound.). Flip a switch and choose which source you’ll hear on your HDMI display without moving cables. Also, you can choose to hear the original HDMI audio through the pass through feature.Note: To ensure the proper transmission of audio, you need to select the corresponding audio input channel.
- 【High resolution】 Resolution up to 18GBPS 4K@60Hz 4:4:4; also supports 1080p, 720p.Supports the use of DVI to HDMI cables to fuse DVI signals and audio signals into HDMI signals.Note: Only the video signals from the HDMI port or DVI port can be input. The video signals from other ports, such as DP and VGA, do not support the use of conversion cables.When there is no HDMI input signal connected, connecting the HDMI OUT to a monitor will display the original colored lines. This displayed screen serves as a prompt that no HDMI input signal has been detected.
- 【Audio formats】 The HDMI port will pass through all digital/analog audio such as PCM, LPCM, Dolby and DTS. The optical audio input supports Dolby DTS and PCM. The 3.5mm audio input supports 2 channel stereo audio like PCM.Note: Only the audio output port can be converted, and the audio format cannot be changed. For example, if the 3.5mm port is a two-channel audio input, the audio output via the HDMI port after conversion will still be two-channel.The audio input channels corresponding to the dipswitch positions are as follows: "Line" means the audio uses the 3.5mm port, "Optical" means the audio uses the optical port, and "Pass" means the audio uses the straight-through HDMI port.

### ⭐⭐⭐⭐⭐ Works well with our system
*by A***R on November 19, 2025*

Great sound quality

### ⭐⭐⭐ Works, but doesn't support CEC
*by L***P on July 18, 2025*

This works as described, but it doesn't support CEC. I used this to combine my AppleTV with a Karaoke system and although it replaces the audio properly, I lost CEC functionality between my AppleTV and my TV/Audio system. CEC support is important to me and the description says it supports CEC. The little booklet (manual) that came with the device doesn't say it supports CEC, so the Amazon description is misleading.
