This converter supports high-resolution sound up to 192KHz/24-bit for both input and output audio signals.
  • [Simultaneous Audio Conversion] - This USB to SPDIF Transmitter and Receiver enables seamless audio transmission in both directions - from USB to SPDIF and from SPDIF to USB - providing maximum flexibility and convenience for your audio setup.
  • [Only for Stereo Optical Transmission] – Please note that the adapter is ONLY for transferring stereo audio signals, and does NOT support 5.1 or 7.1 surround sound.
  • [Plug & Play] – This device requires no additional drivers or software. Simply connect it to your USB source and your SPDIF audio system, and you're ready to enjoy high-quality audio in both directions.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
