It is definitely working, but in case you are wondering if it would work with digital input in audio interface (to gain those extra digital inputs) to work in digital audio workstation, it would have problems. It would only work in 48khz, and even then, it would case some weird syncing problems when the other (analog) channels in your project are pitched up. It is not sellers fault, as this device wasn’t purposed to do what I described. I just bought it to test if it would be easy and cheap way to gain 2 extra channels on audio interface (in my case - NI Komplete Audio 6) and apparently it is not, so beware music producers ;)
Very nice product
