DSD TECH SH-AU01A USB to TOSLINK Coaxial Optical Audio Adapter

I'm using this item in a recording studio for plain ol' reference monitoring (no high-bitrate stuff), and it does the job perfectly. I've not tried the coax output, we're running just the optical. Seems pretty solid and indestructible.

I bought a set of KEF LSX powered speakers a few years ago, not knowing that my options for connecting them were optical, Bluetooth, and wifi. I scrambled for a bit trying to find a sound card or USB audio device with optical out. I could only find expensive options. I discovered that my motherboard had optical out later, so all was well.Cue this year, I went with a smaller motherboard for my machine. My foresight and planning prowess came back to bite me though, and I found myself without an optical connection.This fit my need perfectly. I had been running the speakers using Bluetooth while I was waiting for this to come in, and the difference in quality was amazing.Setup is as follows: plug it into the computer, connect the optical cable, select "USB AUDIO CODEC" as your output, and you're done. No fuss.Build quality is great too. Feels overbuilt, quality connectors and hefty aluminum enclosure.

Did the job perfectly! Rock solid device.

I have been through a few converters...looking for USB to Optical for a soundbar from my computer. I have purchased several in trying to find the one that correctly, and this one does. Others will do Analog to Optical, but you lose sound quality and the volume does not work right, another one disconnects at times. I have not had this one long, so I can't comment on long term issues such a disconnect, but so far it is the best of all. In the computer sound settings on Linux/Ubuntu this gives me two options, analog and digital, with the analog having the same volume issues as my other one, but it works. However, this one gives me the proper digital setting as well, of which is the right setting these converters should provide, and it gives me the best sound, the volume and everything is normal and good. There are so many of these devices that simply don's work, and this one does, and works well and correctly giving the digital connection.

My new computer didn't have an SPDIF optical or coax out so I added this and it did the trick. This converter appears to your computer/device as a sound card. No drivers are needed for Windows. Simply plug it in and it works. You select the sound card (in Windows sound settings it's called "USB AUDIO CODEC") and sound from the PC or device is sent out the optical and coax outputs.If you want audio quality better than 16 bit at 48k (this converter's max) then you need to look elsewhere. Amazon does sell The Douk Audio U2 Pro SPDIF converter for $69 that can do 16 to 32 bit at 41 to 384 kHz which covers all premium streaming sources and high-end song formats.I didn't notice any audio difference between my old computer's built-in SP/DIF and this converter. I haven't tried it but you can use both the optical and coax outputs simultaneously.

so this device does what is says it does, and that is take audio via USB-C and output as digital audio through toslink. I got this for my M4 Mac mini as a way of connecting to my KEF LSX speakers which have toslink input. Problem turns out is you WON'T be able to control the volume anymore with the Mac.There is another adapter that does the same thing (usb-c to toslink) that does allow you to control he volume through the Mac so might end up getting that. For now though going to just stick to using my Apple USB-C to 3.5mm line out dongle and connect it from the back. Side by side with the toslink audio I couldn't hear any difference anyway so returning this adapter.

I used it with my macbook, and it works very well, the connection is easy, just plug and play, no driver needed.

I bought this because I am nursing along an old laptop running Windows 7 and it is not compatible with my newest DACs. This item will do for my purposes, but I wish it supported higher sample rates. Mostly I use the old laptop for steaming radio stations at a 44.1 kHz sample rate. I occasionally stream from Qobuz which features high resolution files at higher sample rates. Qobuz automatically degrades to a sample rate compatible with the adapter so it does not keep me from hearing the music I want. But if I want to enjoy high res files at their best, the limitations of this adapter will cause me to go to a newer laptop running Windows 10 or 11. I have an old USB to SPDIF converter that supports sample rates up to 96kHz, but it is getting mechanically rickety and I wanted to back it up before it broke altogether.I like to use SPDIF signals because I can split them and transmit them to DACs located in different rooms over fiber or coax cables. I like that this item offered both coax and Toslink outputs so I can use the signal locally and remotely without an external splitter.
