HDMI to DVI Audio Extractor

This converter takes an HDMI source from a PC, Apple TV, Blu-Ray player, PS4 or set-top box and splits it to a DVI-D video output plus separate audio paths. It is built for users who need to connect modern HDMI devices to displays that only accept DVI while also routing sound to an external system. The unit handles 1080p video and passes DTS, AC3, PCM and LPCM audio formats.

1080p Video with Dual Audio Outputs

The adapter accepts one HDMI input and provides three outputs: DVI-D for video, a coaxial SPDIF port and a 3.5 mm stereo jack for audio. It supports 1080p resolution and the listed multi-channel audio formats, giving headroom for standard high-definition content. It does not handle 4K or HDR signals, so users with higher-resolution sources will need a different solution.

Upgrade from Basic HDMI-to-DVI Cables

A simple passive cable carries only video and leaves audio trapped in the HDMI stream. This extractor adds optical and analogue audio breakout, making it worthwhile when a soundbar, AV receiver or powered speakers must receive the soundtrack separately. The step up is justified only when separate audio routing is required; otherwise a direct cable is simpler.

Questions about this item

Will this converter pass 1080p video from my older DVI monitor while extracting audio?

The unit accepts an HDMI source up to 1080p and outputs DVI-D video plus separate optical SPDIF and 3.5 mm stereo audio, so your DVI display receives the picture while both audio paths are available.

How can I verify the extractor is active after connecting it?

Power the converter, feed an HDMI signal and check that the DVI monitor shows an image; then confirm sound from the optical SPDIF port or the 3.5 mm jack to prove audio extraction is working.

What cables come in the box and which ones must I supply?

Only the converter itself is included; you will need to provide an HDMI cable for the input, a DVI-D cable for the display, and either an optical Toslink or 3.5 mm audio cable for the sound output you prefer.
