avedio links 8K HDMI Audio Extractor Splitter - 8K/4K Audio Conversion

In this review the avedio links 8K HDMI Audio Extractor Splitter is evaluated for users who need simple HDMI loop output plus discrete audio feeds for soundbars, receivers, or speakers. The single biggest reason to buy is its ability to pass ultra high resolutions while extracting audio to Optical Toslink and a 3.5mm jack, which makes it practical for setups where the display cannot handle or pass audio to an external sound system. Setup is plug and play for most devices and the unit targets home media players and consoles.

Key Features

• 8K and high refresh support: Passes up to 8K@60Hz and 4K@120Hz to a display, useful for high-resolution sources and futureproofing a home theater.
• Wide audio format support: Handles LPCM 5.1/2.0, DTS-HD, Dolby Digital, and Dolby TrueHD so multichannel streams can reach compatible receivers or soundbars.
• Multiple audio outputs: Provides Optical Toslink SPDIF and a 3.5mm analog output so users can connect both modern digital audio gear and older amplified speakers.
• EDID copy and mode switching: EDID copy and PASS/2.0CH/5.1CH modes let users force compatible audio formats for equipment that requires specific signals.
• HDMI 2.1 bandwidth: HDCP 2.3 compliant with up to 48Gbps bandwidth to maintain signal integrity with HDMI 2.1 sources when using proper cables.
• Compact plug-and-play packaging: Ships with a 5V/1A power adapter and is designed for quick setup with common set top boxes and consoles.

Who It's For

The extractor is best for home theater owners, gamers, and streaming box users who need to route high-resolution video to a TV or projector while extracting audio to an external sound system. It suits people upgrading to HDMI 2.1 gear who want to preserve multichannel audio for an AVR or soundbar without relying on the display's audio return.

It is less suitable for users who require built-in advanced DSP features or guaranteed compatibility with every legacy AVR; some customers report occasional audio handshake issues or downgraded picture when cable choice or EDID settings are not matched. Those needing a zero-configuration professional matrix may look elsewhere.

Pros & Cons

Pros

• Passes very high resolutions including 8K@60Hz and 4K@120Hz for modern consoles and players.
• Supports a broad set of digital audio formats for multichannel setups.
• Offers both Optical Toslink SPDIF and analog 3.5mm outputs for flexible connectivity.
• Simple plug-and-play design with included power adapter keeps installation quick.

Cons

• Some users report occasional audio dropouts or no audio signal in specific setups, so EDID switching may be required.
• To reach full 8K capability you must use an HDMI 2.1 cable within 10ft, which adds a required extra purchase for some buyers.

Specifications
