I have the Arturia AudioFuse, but I wouldn't buy it again. As I haven't had the possibility to test it with other hardware, I'm not sure it's my interface or my computer which is the problem.
I'm routing my Windows system audio through my AudioFuse and when watching (for instance) a YouTube video and in the same time working in any of my DAWs, the sound can suddenly drop and the video stops playing. The sound keeps playing in my DAW, but to get the sound back from my system (may be any other non-ASIO application) I need to power off the AudioFuse and power it on again.
This seem to happen sometimes when the CPU load rises (does not have to spike), but it can also happen just when switching applications, or opening another tab in Chrome.
My old Roland QUAD-CAPTURE UA-55 did not act like this, and it is an old interface that cost 1/3 of what AudioFuse cost. Arturia is not much of a help, just the "standard" tips on how to optimize. They won't listen when I tell them I didn't have any troubles similar to this with my old interface, on the same hardware (and Windows 10 Pro 64-bit), with drivers and a firmware from 2014.
It seems like AudioFuse more or less is abandoned when it comes to drivers and firmwares. It has been on the market for a year or so, but the latest firmware was released in July 2018, and the software in September 2018.
