Dingsun Digital to Analog Audio Converter Optical to Analog Converter with IR Remote, DAC Converter Support 192KHz/24bit Compatible with DVD, PS, Plasma, Blu-ray, Home Cinema Systems etc.

THIS is the product that worked for my Samsung 4K Smart TV (UN43TU7000) to get audio to my old Bose Companion 3 speaker/sub system. Someone else posted a review with photos of the same Bose system so I had a feeling it would work and IT WORKS! Came with a power cable and plug so I connected that to the converter box first, saw that the LED power light was on, then plugged the included Toslink cable into the back of my TV and it clicked securely in (another converter system DID NOT securely go into my TV digital optical port and I couldn’t get sound with it, so as soon as I heard that click I knew this was already the better purchase). Then I connected the other end of the Toslink into the converter box and switched the output selection to ‘Toslink’ with the ‘Select’ button on the front of the box (options are either ‘Toslink’ or ‘Coaxial’). THEN I plugged in my 3.5 mm aux cord from my Bose subwoofer and BOOM!! immediately produced perfect sound out of the two Bose speakers that are connected to the sub. also has sound coming out of the TV speakers at the same time. I didn’t even have to go into my audio settings. I can have it play sound from both the TV speaker and the Bose system if I leave Sound Output set to TV Speaker and Digital Audio Output Format set to Auto. If I want just the Bose I change those settings to Optical and PCM. If I want just the TV speakers I can just use the remote to turn off the converter box.The remote is awesome and allows you to control the output from the Bose speakers and you can also still use the Samsung TV remote to control sound coming out of the TV itself. I can adjust the volume on the converter box either manually or with the remote, the Bose control dial (requires getting my lazy butt up), and my TV using the Samsung remote to get the perfect audio output for any situation. SO HAPPY THIS WORKS! so far no issues with Hulu, YoutubeTV, Netflix. no audio delays.
