SPDIF3 sleep issue at windows 10

[kanta]

I'm using SPDIF3 without external power supply, only usb at Windows 10

An hour after entering the sleep mode, SPDIF3 stays YELLOW LED(Not playing) even though play music. There's no sound.

Can you check this out? When I use sleep mode with other DAC, there's no problem.

If I unplug and reconnect the USB cable that is connected to the device, the sound will only come out.
