Hi. My Ultra's output is set to USB as it's feeding my external DAC.

It appears that when the awiim os off or in Standby mode, it continues to send some type of signal to my DAC, so it never goes to sleep.

My request is for the USB port to completely cease all communication/power sending to the connected device (a DAC in my case) so it can go to sleep alongside the Wiim.

Thanks.

Does your DAC have an auto-shut down setup option when no input signal is detected?

The USB 5V is the issue not the input signal. I had the same issue when using a Topping E30 with a Raspberry Pi Squeezelite player. A udev power rule fixed it.

I knew someone would ask about that 😃. In Linux you can add rules that control what happens when a USB device is connected. I have no idea how to do the same on a WiiM device. Everything is described here
It is quite hard to follow.

Before all, thx for your reply. I completely agree, quite hard? :unsure: Almost impossible to follow 😂
Anyway, not for me. I’m on IOS; Android; Windows 11

Thanks a lot for the explanation. I hope Wiim adds something like it as a feature, so we can get our external DACs to go into standby.
