SMSL PS100 Digital to Analog Audio Converter, USB/Optical/Coaxial/HDMI ARC to Stereo L/R RCA Output DDC Digital Toslink SPDIF 192kHz DAC Converter for PS5/HDTV/DVD/Blu-Ray Players/Home Cinema Systems

I struggled but ultimately gave this a 5 star and this more of a "How To"/"Do & Don't" Guide than a "review".TL;DR: I think this is an absolute steal for price and features but ARC is a pain to set up/keep working (probably extra problematic for "smarter" TVs like my LG C4). In the end, I was able to figure it out after much experimenting and hopefully the pain is behind me once I can "set it and forget it".I have not tried using coaxial input but tried Bluetooth, optical and USB inputs a few times. HDMI ARC is what I tried the most.I can't really say much about audio quality... It sounds fine to me and I can't tell if there is any difference from direct optical cable going into my Yamaha RX-V3800 receiver vs HDMI/optical going into this then feeding RCA into my receiver which ultimately drives a set of Klipsch RP-600M II speakers. I also didn't really try that hard to stress the DAC on this unit.There is conflicting/misleading information on volume control... I think it is technically correct that you can not change the volume of the connected devices but I can mute or reduce the volume of the RCA output with TV remote so it effectively gives me limited volume control with TV remote in the end (this is the main thing I want out of all this).Customer service did get back to me with a fairly detailed answer but still a rather generic answer (not that I included TV model in the inquiry). Here is my experience/recommendations with a LG C4 TV:1. unplug all HDMI ports2. plug compatible ARC/eARC HDMI cable into eARC HDMI port (HDMI2 for in this case)3. connect other end of the cable to unit (PS: make sure HDMI input is selected on unit)4. TV should say something like checking HDMI2 device5. change/make sure TV is set to use wired speakers/HDMI6. under advanced settings, select PCM under digital out settings and turn off eARC support (DO NOT change anything else) (PS: it also worked for me leaving eARC on...)7. unplug HDMI cable from unit and plug back in8. TV should say something like checking HDMI2 device again9. power off TV (ideally unplug TV even as it sometimes go into standby mode rather than truly powered off)10. power off unit (hold power button for a few seconds)... been doing this so long I totally forgot about making sure unit has HDMI selected also...11. power back on unit (press power button)12. plug TV back in and power it back onFor initial setup you might be able to optimize the ordering/steps here but this is what I do when things stop working and is what is most fresh in my mind so...Now TV should say a soundbar is connected to HDMI2. Going forward, unit does need to be on before TV whenever you turn off TV. Otherwise if TV is turned on with unit off, you'll need to turn off TV and turn TV back on.Problems I have seen with my LG C4:a. having other HDMI ports connected can interfere with the setup/"paring" processb. plugging back in other HDMI ports sometimes cause the LG C4 TV to revert to default settingsc. checking sound settings help but often times there is no visible change in TV settingsd. changing other HDMI input settings also seem to cause problemsHope this helps at least one other person out there but maybe it is just for me to remember how to make it work specific to the LG C4?

Works with the TV remote (if your TV has the capability), sounds wayyy better than other HDMI dacs I have tried. Perfect for connecting an old receiver or amp that doesn't have ARC to your TV. For the price I really haven't seen anything close in terms of value, any of the dacs the are better are considerably more expensive. This is also just an good all around budget dac for a computer or any other device for this price. But I think the real use case where this dac shines is being able to cheaply integrate your TVs sound into your older hifi equipment. Also make sure your TV's ARC is set to PCM signal or you may run into issue.

This is my first experience with an hdmi dac / audio extractor, so I'm not 100% sure if the problems I'm having are par for the course or not, but I've encountered a few issues with this item not working how I'd expect at least:1) the lights on the front turn off after a while and clicking the input-selector button doesn't re-awake them. It still seems to function properly with the input that had been selected when the lights went off, but at that point there's no way to see what input it's set for without powering it off and back on, which leads us to...2) when the device is powered off it loses memory of what volume it had been set at before. So if 100% is really loud as it should be, and the volume typically sits at 50% for normal listening volume, then you have to keep this device powered on 100% of the time or else you'll randomly wake the neighborhood when it turns out something in the background is playing audio when you power it up3) At least on our TV, a 7 year old Sony, when we turn the TV volume up or down it moves in incriments of 6 whereas before this device with audio being output from the headphone port to an amp, volume went in increments of 1. So there's much larger jumps in audio level each time we hit the volume now. This may just be normal for these types of devices, I'm not sure4) Today audio just stopped completely. We didn't want to power cycle it for reason #2 above, but cycling through the inputs was difficult for reason #1 above. I don't know why this happened either which is concerning, we've only been using the device about 2 days so far. When I clicked the input button the first time the TV popped up saying that it changed back to TV speakers from external speakers - seeming to indicate that the TV was doing what it's supposed to be doing and the problem was with this device not processing the audio it was being sent. Went we clicked it enough times the TV returned to saying it was sending to external audio device, so again the TV seemed to be doing things right here and we've never had a problem with external speakers on this TV in the 7 years we've had it. If this issue continues we'll probably send the device back as it's just too much to deal with especially with the other issues.
