No audio

[mcoak]

I've been using the WiiM Pro since December with no problems. After returning from a weekend trip I couldn't hear my music when streaming to Pro.
Did a factory reset, everything went well. Still no audio.
Connected the BT receiver previously used to see if the problem was the amp. Music playing as I type. So it's not the amp or cables.

Any thunderstorms pass through while you were away?

No thunderstorms. The WiiM is plugged into a UPS.

Did you checked all outputs?
Maybe You accidentaly turned mute on?

WiiM support determined the Pro was defective. Replacement arrived promptly.
Thanks to everyone who suggested solutions!
