UCSTR-B3 USB to SPDIF Input Output Adapter, 2-in-1 USB to TOSLINK Optical Transmitter Receiver Compatible with MacBook, Laptop, Computer, PC, Stereo Sound ONLY, NOT for Phone or Tablet

ATTN in win10 / win11 settings lower your sample rate to 20bit/48k to get these to work perfectly. Which is normal headset sample rate anyway. I do wish 96khz/24bit would work but anything higher then 20/48 just outputs distortion im sure 2rd part software might fix this but I personally could care less (I have a vary long 12' run you may be able to get away with higher sample rates with shorter better cables) I have two of these connecting my laptop to my desktop via two SPDIF cables 2 for input & 2 for output in the reverse direction. EVERY desktop PC has ground loop issues via its PSU not including the rest of your house this device REMOVE the grounding hum by removing the ground. I always always always had to overbuy in the past via soundcards DAC / 14" Grounding rods / ground loop / breakout boxes / ground isolators / UPCs. Spending thousands over my lifetime to get rid of hum especially im 60' away from a power station. When connecting 2 PCs. THIS device is a life saver & so extremely simple I am in love. I will not only be saving seller but investigating the manufacture as well for their ideology when approaching other tech with this simplier minimalistic design. YES it only has 20bit sound sample & yes optical SPDIF is kinda outdated (HDMI is only way to send 96/24+) BUT headset & most systems don't allow you to use higher sample rates anyway. I was actually designing this device when I found it on amazon its so easy to run SPDIF out. But THIS is all i needed NOT dozen extra features I don't want to pay for.

UPDATE - screen saver / sleep issue in Windows 11 and workaround: After using this adapter for a while I discovered that this device prevents my screen saver from activating and my display from sleeping. I was able to work around it by disabling the associated USB Input Device in Device Manager. Once disabled my screen saver activates and my display/PC will go into sleep mode again, and the device still works. This seems to be a common issue with some other USB DACs which is what led me to the workaround. This USB digital converter does just what it advertises at a reasonable price point. It is plug and play in Windows 11, showing as a generic S/PDIF in and out digital audio interface up to 24bit 192 kHz supporting DTS and Dolby Digital pass through to digital receivers (did not test either of those). Although using a Savitech chipset (9123L as confirmed by Cubilux support) it unfortunately does not supply ASIO drivers. A very similar product that does include an ASIO driver would be the Hifime S2 Digi which supports up to 32bit 384kHz. However I can't really dock points on this Cubilux since it doesn't advertise ASIO support and is priced accordingly cheaper. The construction of the Cubilux vs the S2 Digi is a bit nicer since it is made of metal instead of plastic, and uses a USB-C input port instead of Micro-USB. Works reliably for my application which is to provide a simultaneous stereo S/PDIF input and output interface for an old MOTU Audio Express device whose vendor-provided USB Windows drivers crackle and often fail to load after wake from sleep. Contrary to what it says on the listing it is actually also plug and play in Android on my S24 Ultra where I was able to access both the output and input. Same on Ubuntu Linux. Hopefully Cubilux will consider ASIO support in a v2 update.

Muy buena calidad de producto y sonido

The Cubilux UCSTR-B3 is just what I needed to transfer music from my computer and other music sources to my various collection of minidisc recorders.

Wow, if you need optical to USB this does the trick. Windows is an annoying pain and you must get Bit depth and rate matching otherwise audio is wonky. Once your settings are correct it works great.

In general, it does what it is supposed to do without any hassles. It is stable and does not require any drivers. But there are two issues which might be deal breakers for some users. First, it does not clock to external source and does not go higher than 48 KHz. If you are pairing that with some audio interface, that might cause crackles. Second, and that is more serious, somehow it does not let Windows to go into sleep mode. It looks like that it emits some events all the time, so, no matter what power setting you choose, your Windows never goes to sleep. If you put it to sleep manually (through the menu or clicking on hardware sleep button) it sleeps; but eventually it wakes up. I have stopped using it (replaced with RME Digiface USB, which is way more expensive though), and the sleep issues went away right after I disconnected it. So, the bottom line, the lack of sync is expected for this price range. But preventing PC going to sleep is some serious issue. So, two stars.

Rigged and built to last

Un aparato muy pequeño (menos que un mechero tipo Zipo, pero que funciona a la perfección. Lo he configurado para trabajar a 48Khz y 24bits en Ubunto (por medio de la terminal y con ayuda de la IA) y he conseguido recatar mi viejo previo MindPrint que no tenía puerto USB. Recomendado!
