Digital to Analog Audio Converter-192kHz Techole Aluminum Optical to RCA with Optical &Coaxial Cable. Digital SPDIF TOSLINK to Stereo L/R and 3.5mm Jack DAC Converter for PS4 Xbox HDTV DVD Headphone

I feel like the people who are reviewing and saying that this product doesn't work for them don't realize why it doesn't work. The product description reads "Supports uncompressed 2.1-channel PCM or LPCM digital audio signal output, will Not supports 5.1 channel Dolby sound". If your TV doesn't have either PCM or LPCM modes, this product probably won't work for you. These modes are the ones that are able to receive the signal sent from this converter. I had to look in the advanced settings in my TV in order to find it. At first I wasn't getting any sound, but once I did some digging through the settings and changed it to PCM mode and the sound comes through just fine.

I am very happy with this Device, I have surround sound one again

I needed this converter because my new sound bar was not compatible with my existing TV. PLEASE BE MINDFUL, it comes with a USB power cord but It does not come with the piece needed to plug into the wall. I had a spare, so it was no big deal BUT this is not mentioned in the details. It's a lot smaller in person which is great. It is easy to conceal on my entertainment center. Like the title, it gets the job done.

I bought this to connect a pair of wireless headphones to a TV that only has an optical output jack. I was concerned that there might be some time-lag (latency) but the unit performed perfectly. It's also very solid and well made. I would definitely recommend it. Please note that it does not come with its own power supply and needs a micro-USB power adapter. I have boxes of them, so it wasn't a problem.

Had high hopes that this would work for me, since my BOSE sound bar, which was only 14 months old, crapped out on me. Thought I would order this to hook up to my BOSE radio (while waiting for my sound bar to be repaired and sent back to me) -- didn't work. Even tried a 3.5mm, or whatever the h*ll mm it is auxiliary cable -- NOTHING. Also tried hooking it up to two BOSE external speakers I've had for years that still work, and I have hooked up to my other two TV's -- NOTHING. All I can say is, there is absolutely NO NEED for this "optical line B.S." with these new TVs. Just another CROOKED RUSE to get people to spend more $$$. With my older Samsung 32" LED TV, all I had to do was hook up an auxiliary 3.5mm cable between my TV and my BOSE radio -- excellent external sound. NOT NOW. TV manufacturers had to add this optical line UNNECESSARY B.S. And don't even get me going about BOSE -- BUYER BEWARE. DO NOT BUY THE SOUND BAR SOLO 5 -- IT'S GARBAGE! Since THIS little PIECE OF CRAP didn't work for me, I'M SENDING IT BACK AND I WANT A FULL REFUND. I could kick myself for spending a few extra bucks to have it shipped in 2 days. I'm glad it worked for those of you with ancient, archaic Pioneer and Kenwood stereos that they stopped making back in the 80's -- OMG. IT DIDN'T WORK FOR ME -- SO BACK IT GOES!!!!

I've got a small, 15 year old 5.1 surround sound system that lacks a digital optical input to receive sound from my TV, the 5.1 just has the old white/red RC stereo female inputs. So when I got my new Sony Bravia 4K TV, I wanted to be able to listen to my TV speakers without having to change anything but turn on my surround sound unit when I wanted to. I also wanted to play the sound out of my TV speakers along with my 5.1 sound.This adapter from Techole does the trick, taking my digital audio output from my Sony TV and then I can use an RCA cable to connect to my 5.1. There is no lag so far although I did detect a tiny echo (so there is a little bit of lag) between my TV speakers and 5.1 system. I was able to power the adapter using a USB-power source that I had in the same cabinet so no problems there.I'll update this review if I experience any issues.

The build quality appears good with a nice metal housing. The fact that a power supply was not included was not an issue for me as I had loads of unused USB AC adapters laying around anyway. The inclusion of the optical, RCA and micro USB cables was nice and the length of the cables was adequate for my needs.Sound quality is very good.There is no volume control on the converter, so volume must be controlled either on the soundbar / stereo / whatever or the TV (or whatever) must be set to variable output of the audio (vs fixed).Now for the tricks...1. Make sure to remove the clear plastic protectors from the ends of the optical cables before inserting the cables into the devices. The protectors are not particularly obvious at first glance as they are clear and small - you have to look carefully.2. Make sure to set the output of your TV (or whatever) to PCM. There may be a straightforward setting on your device that says "PCM" or it may be less intuitive - something like Dolby - OFF.3. In my case, I was connecting to an old Sony KDL-40R450A TV. There was NO setting to force PCM output (only) though the TV manual did clearly show the output as being PCM / Dolby.Try as I might, I could not get the unit to produce any audio from either of the two devices providing input to the TV via HDMI - an old TiVo Premier and an Amazon FireStick.I took the unit to a different TV and verified that the unit and included cables were in fact functioning correctly so I boxed the converter and cables in despair, assuming the problem was with my TV.Being hard headed, I decided to give it one more try and discovered the last secret:4. Turned out I had to make changes to the audio settings on the Firestick and TiVo to disable Dolby / Force PCM rather than changing settings on the TV!Amazon Fire Stick - Settings, Display & Sounds, Audio, Dolby Digital Output - changed from default of Dolby Digital Plus Automatic to Dolby Digital Plus OFF.TiVo Box - Settings & Messages, Settings, Audio, Dolby Audio, PCM only (no Dolby)
