Works just as expected. Easy to install. Sounds good. ### ⭐⭐⭐⭐⭐ Works with sonos ray and MacBook air m4 *by P***W on 30 January 2026* I got this to hook up my sonos ray as only input is optical, my MacBook is connected to Monitor via displaylink and adapter connected to monitor via usb, i then set MacBook sound output to usb in settings, also changed monitor sound output to usb, sound quality and connectivity all good, easy to install, good quality. ### ⭐⭐⭐⭐⭐ Cubilux works perfectly and performs as promised. *by A***R on 25 December 2025* Age (mine) caused me to buy this. I listen to Amazon Music on my Hi-Fi via a Wiim Pro Plus streamer. I like the sound but although the controlling App for the Wiim is very good, it is not available on a PC. Using a tablet or phone, I have difficulty reading the screen and prefer to see the Amazon Music site online on the 60 inch TV in my living room. I needed a way of getting the sound from the USB outlet of the mini pc attached to the hi-fi into the optical input of the Wiim to take advantage of its AKG DAC. Should have been simply plug and play using the Cubilux and would have been had the said mini PC been attached to a screen. It isn't. The screen is attached to another mini PC connected to to the TV about 12 ft away. The answer was to control the pc attached to the hi-fi from the pc attached to the TV using Windows 'Remote Desktop'. Confusion on my part about which was the host and which was the receving PC led to 2 or 3 hours of changing and mixing settings before getting it right. The cubilux, completely oblivious and unperturbed by my confusion just worked. The sound is perfect and delivering the promised full 24 bit 192 khz to my hifi via an interface which is fully legible and straightforward. Summation, the Cubilux is simple, straightforward and effective. Me, not so much. ## Frequently Bought Together - Cubilux USB A to TOSLINK Optical Audio Adapter, Unidirectional USB Type A to SPDIF Digital Converter, S/PDIF Transmitter for Computer Laptop PC ONLY, NOT for TV Or Other Devices - KabelDirekt TOSLINK – Optical Audio Cable – 6ft – Fiber Optic Cord, S/PDIF Digital Audio Optical Cable for Soundbar, Stereo Systems, Home Cinema, Xbox One/PS4 – Designed in Germany - Cubilux USB A SPDIF Input Adapter for PC [Stereo Recording ONLY, NOT for Playing Audio] USB Optical Line-in Dongle, Toslink to USB Receiver, USB A SDPIF RX Interface Suitable for Laptop Computer --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/480540293-cubilux-usb-a-to-toslink-optical-audio-adapter-unidirectional-usb](https://www.desertcart.in/products/480540293-cubilux-usb-a-to-toslink-optical-audio-adapter-unidirectional-usb) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-03*
