4.0 out of 5 stars Works fine with built-in audio drivers
Reviewed in the United States on April 12, 2023
Color: USB DACVerified Purchase
I wanted to connect my Linux box to a digital receiver. This device works great for delivering stereo PCM over S/PDIF, and the built-in Linux audio drivers support it. Coax and optical both work (simultaneously).

Various pieces of documentation are split on whether 5.1 output is supported. I can report that it enumerates configurations for 5.1, and my receiver reports receiving a 5.1 data stream when one of these is active.

I tried the analog outputs briefly, and they sound fine to my ear. I haven't listened for DAC quality because I won't be using it that way.

The product photos show a "power indicator", but I think that might just be a hole to expose bleed-through from the TOSLINK emitter, which seems to be always on, even if you choose a non-digital config. Hey, it works!

There are configurations which include "mono microphone", even though none of the documentation mentions such a feature -- I didn't try this, so while the USB sound chip almost certainly supports it, I don't know if it works on this device.

The packaging is minimal. There's a tiny booklet written in broken English, and I can't figure out what some of the sentences are even intended to mean. There are (minor) contradictions between the product listing, the tech support answers here, the booklet contents, and the front of the box. Don't buy this if you expect a fully comprehensible manual.

In software, it reports itself as "C-Media Electronics Inc.", with the C-Media vendor ID. This is a C-Media chip, on a board with a couple connectors, in a little metal box. That's not necessarily bad (or good), but that's all it is.

This is a nice (and cheap) little box for bus-powered USB to stereo S/PDIF. For 5.1, you may want to use HDMI audio to avoid compression. For analog, you may want a nicer DAC, and maybe a hardware volume control and a full-sized headphone jack. There's really only one use case where I'd choose this device, but for that one use, it works fine.

Does what it should, max fidelity is 16bit, 48KHz which is fine for playback, would be nice if it went a bit higher but whatever at this price. There is no such thing as volume control over optical, at least as far back as I can remember so I wouldn't ding it for that. I'm using to send a clean signal to Bose Cinemate II while plugged into an unpowered USB hub and it works great (highly recommend the combo, these systems are cheap used). Will update my review if it breaks.

5.0 out of 5 stars Excellent!
Reviewed in the United States on September 28, 2022
Color: USB DACVerified Purchase
I'm using this to convert a USB signal from my work laptop to my dac. I like to listen to music while I work, but also want to receive work calls when they come in and switch over with minimal effort. To that end, I intended to use usb out from my PC (for maximum sound quality) into my bifrost 2/64 dac, SPDIF out from my auris audifi to the same dac, and then USB out from my work laptop to the same dac, as well. Problem is that dac only has one USB port. The singular use I have for this box is to convert the signal from the work laptop to coax, the last remaining input port on my dac. This does it quite nicely. I cant speak to the sound quality beyond work calls, but it works spectacularly for that. Recommended, certainly for simple conversion for a similar use case.

You want a digital output? This one is rock solid. Optical and Coax outputs are solid, and will work with no fuss. Line out not tested.
This is not the $300 DAC, but do you need that for a steam deck, PC or TV? if you are a home theatre geek you're already got something else, but for the rest of us who want a digital output this will do great.

5.0 out of 5 stars Does the job beautifully on Linux
Reviewed in Canada on March 8, 2024
Color: USB DACVerified Purchase
I am using this external sound card on Linux Mint 21.2 for sending digital audio from a USB port to my Behringer MS40 amplified speakers via a TOSLINK digital link. Wonderful sound! This unit is versatile : sends output to RCA (analog) or TOSLINK/coaxial (digital). Not too expensive, great buy ! I have briefly tested the analog output (through RCA) and it worked fine although the sound was loud. But that can be adjusted with your operating system.

Buy with confidence!

5.0 out of 5 stars No more ground noise
Reviewed in Japan on May 2, 2024
Color: USB DACVerified Purchase
Bought this because I needed to connect my laptop to the audio interface via optical cable, because I had ground noise when connecting it via analog headphone jack. And yep, no more ground noise. Finally very clear sound!

One thing to mention, is that digital outputs (via toslink/spdif) won't allow you to control volume from your computer. But that's normal, and not a problem of this particular device. The reason is that lowering volume "digitally" will also lower audio resolution of the output sound, and that's probably not what you'll want to get. So yeah, just use volume control on your audio interface (soundbar, etc) (or you might want to install third party volume control app, that's an option too)

5.0 out of 5 stars Great sound, very powerful preamp inside... you may need to be careful
Reviewed in Canada on May 14, 2021
Color: USB DACVerified Purchase
I hooked this DAC up to my Daphile music playing PC system, then hooked it via RCA jacks into my stereo... and nearly blew out my headphones (which were thankfully NOT on my ears)... Using the software volume settings, I find this does best at about 28% volume - much louder and it starts to overdrive my amp's input.
The earphone jack gives even cleaner sound than the RCA outs fed into my stereo and listening on headphones to the stereo, but I'll likely just listen through the stereo for ease of use. For anyone that travels with digital music (MP3, WAV, Apple) and listens to headphones (e.g. at work, in a hotel), these make an enormous improvement over the headphone jack in your laptop. Plus, if you want to integrate really high quality playback from a PC into your Home Theater system you have both Fiber Optic and Coaxial (which is amazingly even cleaner than Fiber), and most HT receivers have these inputs. Very pleased, well built, good price.
