This is exactly my experience, when USB is plugged, you cannot play from coaxial. it sure will charge but will not play.
1. USB audio+power supplied (eg from PC) then SPDIF becomes output
2. USB power ONLY supplied (eg from USB charger) then SPDIF becomes input
That is it really. If there's a struggle still, just open an STS ticket here: http://support.ifi-audio.com
I thought I am the only one who has this problem, I then search the whole thread and found several posts mentioned the same problem. I have "two" iDSDs, one silver and on BL. Both have the same problem. It seems like only older firmware 4.0.6 supports what iFi audio says. I think I'll return my iDSDs. It is rather disappointing.
How many people are able to play from "
Coaxial" input while connected to a usb charger?

I had the same question, in post #4664 on page 311, and never received an answer.
My only "solution" thus far is to use a powered USB hub with individual switches for each port. Whenever I use the iDSD's optical input, I make sure the hub's port that's connected to the iDSD is switched off. This way, at least I don't have to be be connecting and unconnecting the USB cable all the time.
After an extensive back and forth with IFIs technical support they suggested I try different versions of firmware, and finally an older version
4.06 solved the problem .... Make sure you wait for like for 5 seconds for signal from optical input to come on.... The instructions are there on their support page as are several firmware versions.... Hope this helps!
