Some Q&A:
1.After connecting it through Optical with my TV and amplifier, no sound come out
- Please check your TV's settings,the sound output should be setted to be external amplifier,not TV speaker,or else no sound
2.sl and sr output same audio no seperation
- Please check your audio source and switch the audio mode from 2.1 to 5.1,usually it base on your audio source's definitions;
3.Does not properly decode DTS/Dolby to analog 5.1 channel sound. All speakers have the same signal.
- Switch the audio mode from 2.1 to 5.1, also check if your audio device can support output the DTS signal(RAW/Bitstream/Digital)
- Please use digital signal port,such as SPDIF/Toslink/Coaxial ports, Not Analog signal port,such as 3.5mm aux Jack
- Avoid another digital cable from your device directly connected to your audio devices.
4.Signal noise on the output
- Check the quality and connections of cables,reconnect the cables stable;
- Avoid another cable connected from your device directly to your audio devices at the same time(or else there would be niose at beginning when power on).
5.No volume control
- There is no volume control on this decoder,please using amplifier together with it,or else mini sound.Amplifier is required;
6.SW sound output：Base on your audio source/format,please use subwoof and volume in a good status;
7. In Dolby/5.1CH(6 channels) REAL SOUND SURROUND status, all 6 channels are separate channels and different sound effects.For example,CEN are " people talking", SL+SR are just some "movie background sound",different movies,different signals or definition,and it doesn't mean that the CONVERTER is "not working" or "No Sound".Amplifier is required, or else,in 5.1CH, SOUND IS VERY TINY.(THE CONVERTER IS ONLY FOR 5.1CH DECODER,NOT AMPLIFIER,NOT 7.1CH)

As advertised, decodes your digital output for 5.1 surround, but for some reason they only seem to last about a year. Then the constant restarts begin. Something in the sound gets wonky, sometimes frequently and sometimes hours apart. Only fix is unplug the power and plug it back in. This is maybe my 5th one because it's a lot cheaper than a receiver.

Feels a little bulky, durable, fairly-built. Easy to connect and configure. Worked well on my a/v receiver, that was hooked up to my PS5. Sound is is okay. On the "DVD 5.1 Channel" format, it won't allow you to change any sound settings whatsoever (equalizer, treble, bass, gain, etc.)Sound is good.When 2.1 mode is on, the front speakers are loud, surround speakers are faded.When 5.1 mode is on, all speakers are the same volume but are not as loud as the front speakers would be if it was on 2.1 mode.

Number one was the adapter which was the wrong connector and very loose. And the cord was very short and cheap. The sound is not decoded but interpreted by the device = it is completely emulated and totally wrong. The button that switches from 2.1 to 5.1 has no indicator and it is not an in/out button. Only plus is that all inputs work = at least produces sound. Save your money

Needed to connect a new tv to an old stereo receiver. It was very easy to setup. No issues getting 5.1 vs 2 channel as some noted.I thought this would be the best connection method, take advantage of the 6 channel input on my stereo. There is one aspect I didn’t think of. there is no method to tune or balance the frequencies of each channel. The cut off to the center and fronts is quite high and thus without a subwoofer connected there is very little bass. Perhaps the alternate method to buy a digital to analog converter and use the stereo’s surround options and settings to get the best sound is a better option for my scenario. But I can’t reduce the rating based that.

I have an old Onkyo AV receiver that does not support Dolby Digital (AC3), but does have 7.1 inputs using RCA.. I installed this DAC using 3 pairs of RCA patch cords (FL,FR,SR,SL,Cen,SW) 5.1 and set the Onkyo to Multi-input.. BAM worked right away. Loud and Clear, 6 channel audio. I tried using the TOSlink and the Coax digital inputs and both are equally effective.. Highly recommend this for older AV receivers. !!

Was trying to use a set of computer speakers for my home theatre setup. The sound floor is awful, the speakers buzz quite a bit at anything more than half volume and they’ll be there a lot because it made the speakers really quiet. While the surround sound effect was really good with great locational audio (sound stage)

The device worked fine for a few months, but now I've got to twist it around into strange orientations in order for it to function - mostly but not quite upside-down for instance.I've taken the board out of the case and used my multi-thousand-dollar oscilloscope to determine whether there's a bad connection e.g. from the coaxial SPDIF or anywhere else on the board, and as far as I can tell that is not the case. From my experience designing and fabricating circuit boards, my best guess is that there's a fault somewhere in the board itself, as I don't see any bad solder joints anywhere.Additionally, when looking at various points on the board with my scope, I see a very clear and significant noise floor that's only a few decibels lower than the majority of the signals I get from a typical DVD. I've traced this back to the power brick itself, so if you care about sound quality with this device, find a better brick.It's been 4 months since I bought this so it's out of Amazon return period...

This is exactly what I needed to convert a smart TV (with only SPDIF) to use a Sony receiver (with no SPDIF input) and surround system I was given. Works exactly how I wanted it to and works flawlessly.It is true that the sound depends on the source, so if the source says 5.1 and it turns out to be something else, you won't get exactly 5.1 surround, but you will still get sound. This has worked for everything I cared about on that smart TV and finally allowed me to use those beautiful speakers built into my walls that came with the house.

I was hoping this device would work, and it does, but it has a hum on all digital inputs, both optical and coax. I tested via my TV audio out, with an HDMI audio extractor, and also with the coax out on a Sony DVD player. Since my Sony DVD player is hooked up to a CRT TV, the audio latency was very evident, definitely more than 1 frame.It also seems to have a problem with short sounds that are followed by silence, like hearing a signal go from a low volume immediately to zero, where it's a slight blip/pop that sounds like DC offset problem. I assume all of the digital to analog 5.1 DTS converters that look similar to this one are based on the same hardware. I won't be taking a risk on another one. If you can handle the noise, it does work, but I can't handle it.

The SOUTHSKY 5.1/2.1 Audio Rush Digital Sound Decoder works great for connecting my stereo Sennheiser headphones. I'm taking 5.1 surround sound from a gofanco extractor and decoding to analog RCA outs. This unit has a switch that combines the 5 surround channels making left front and right front mixed stereo outputs plus subwoofer out. I am finally able to keep surround sound playback in the room and provide headphone audio for my wife. Other splitters I have tried always switched my Receiver from 5.1 surround encoding to PCM stereo when I connected to use the left and right RCA outputs. This unit connected to a gofanco HDMI to HDMI extractor set to 5.1 surround makes my Receiver stay in surround mode so all my devices ( Firetv, Blu-ray player & Dish TV) play out surround sound.

I'll explain my current setup and if you have something similar this device should work well for you. I had an AV receiver in my media room that had a digital coax and an optical audio input. It failed after 15 years but I had an old AV receiver that only had 5.1 analog inputs and I decided to use the sound decoder instead of buying a new receiver. My TV only has coax out and my XBox has optical. Connecting this device to the receiver, TV, and XBox is very easy and I was able to get sound right away from my TV. My old receiver had an indicator that it was receiving multi-channel but the replacement receiver doesn't, just a 5.1 input selector. I know which TV stations broadcast in 5.1 so I selected one of those to test the surround sound. The center speaker did have most of the speech track but I wasn't getting a lot of sound from the other channels. With this receiver I can adjust the volume of each channel individually so I could get the effects that I wanted and it appeared to be providing 5.1. I think that not having this capability lead to some of the complaints that I read about low sound volume. Selecting my Roku connected to the TV I got a full surround effect but my old receiver never detected it as multi-channel which makes me think that this was simulated 5.1. My guess (and it's only a guess) that if this unit detects multi-channel it will pass it through and if not, it simulates it. Overall, this unit did what I needed. It allowed me to connect my TV to an old receiver with a passable sound quality.Here are a couple of things that made me rate this a 4 instead of a 5. I don't like the push button to change from 2.1 to 5.1. Without an indicator it was difficult to determine which mode I was in while I was setting up. I would recommend using a simple slide switch or an indicator. Having a multi-channel indicator would be helpful. When I first set it up, I could hear a low 60 Hz hum through the speakers. I found by moving the power supply away from other AC sources I could dramatically reduce the noise so I would guess that there could be a shielding problem. But, for the price point it worked remarkably well and it allowed me to reuse some old equipment instead of buying new.
