Spdif2 goes to “sleep”

[ACSOUV]

Hi Jim, we did not received any report like the condition you meet.
Hi Adrian, do you have the same issue when you are using an iFi power?

Hi, I continue to use the unit and the “sleep” issue is inconsistent. It will stay on for days, and then it will be off. Unplugging it and plugging it back in wakes it up. I use it with a PS Audio DAC and no one on PS Audio’s forums reports a similar problem. Apos Audio, where I bought it, offered to replace it if Matrix did not have any solutions.
Thanks, Jim

I need to correct my former answer after I bought X-SPDIF 3 (Replace X-SPDIF 2), and I find the same sleep issue.
And I bought element-H last year.
I am sure that X-SPDIF cannot wake up without USB Power.
I guess that X-SPDIF should be waked up by USB Power and then be disconnected when you have an external DC Power.
So, when your USB Port cannot support enough power to wake up X-SPDIF, just like you connect it to a USB 2.0 Port (500mA max), X-SPDIF is likely to go sleep as you said.

The right way is you connect X-SPDIF to a reliable USB port or using a powered USB cable.
