If I manage to get multi-channel sound from the SPDIF, then the device is worth 10 and five stars. But because I see it as a scam...... The sound is clear, the device was immediately detected on Windows 10, but I never got 7.1 from the digital and in the small settings software that is installed with the driver, the only option is PCM. I should clarify that the optical cable goes to an amplifier that automatically detects what I send it and unfortunately it has always been stereo. I probably wasted my money. As for the analog ones, I have no opinion. Using 6-pin RCA cables to get sound from a €40 box is excessive, I think.... That's it, here's to good health
