Amazon Basics Audio Extractor Converter, HDMI to HDMI, Audio (SPDIF + RCA Stereo), Black

Product Information

If your soundbar (or speakers) only has an optical port, then you would want an HDMI audio extractor that has optical out.

On the front, you have 3 buttons (power, HDMI selector, and ARC/auto-switch button). In the middle, there’s a standard 3.5mm headphone/speaker output. On the right end, there’s an array of indicators (power, ARC, auto-switch, 4 input indicators, output indicator) and the IR receiver.Even though optical audio is a digital signal, it can only handle compressed versions of Dolby's surround sound technology.

Additionally, there are some audio extractors that support various types of output such as RCA (analog), 3.5 mm (and some 6.35 mm), digital optical, and of course HDMI. There are also other devices with their own integrated HDMI audio extractor that can function similarly to a standalone version, with some additional features such as audio source and output switching. Remember Format Compatibility Question: Does this unit support HD audio formats like FLAC? Answer:"FLAC is a file format, rather than an audio stream format. Once decoded, it can be transported via any method of digital or analogue means available. This extractor supports the common HDMI audio streams, such DTS Digital, Dolby Digital and LPCM. The remote makes things a little bit easier. It has a separate button for each HDMI input and allows you to enable/disable the auto-switching and ARC features. Things we don’t likeInside the box, you will find your Avedio Links switch/extractor, remote, power adapter, user manual, and a warranty card. Things we like

Thanks for your question. You will need an extractor with at least one HDMI input, one HDMI ARC output, and one headphone output (all the other inputs/outputs are optional). You would have to connect your Roku to the HDMI input, connect your Samsung 4K TV to the HDMI ARC output (use the HDMI ARC input on your TV), and then connect your Bluetooth transmitter to the headphone output.We’re not aware of any HDMI audio extractor that doesn’t require external power supply. In most cases, you get a dedicated 5V DC adapter. Some extractors come with a USB power cable (USB Type-A to micro USB or USB Type-A to USB Type-C) and you’re supposed to plug them into your TV’s or receiver’s USB port for power supply. In our opinion, those with a dedicated power adapter are a better choice.
