Hi everyone,

Just wanted to share my experience with the Fosi K7 DAC and a recent build using the Ryzen 7 9800X3D - MSI MAG B850 Tomahawk MAX WIFI - Windows 11 24H2

The problem:

When using UAC 2.0 , the DAC doesn't wake up correctly after the PC is taken out of sleep mode.

I had to physically disconnect and reconnect the USB cable for it to be detected again.

Switching to UAC 1.0 completely solved the problem: the DAC now reconnects perfectly after sleep mode.

I'm having the same issue. I have found that turning the DAC/AMP off and back on fixes it, so you don't have to unplug the cables and reinsert them at least. I hope this is something that gets addressed soon though, otherwise I'm going to return it.
