Hugo (when Powered On and connected to AC):
1. Charge Light on (white) and Battery Light on (white).
2. Volume Light (green) and Input Light (white) and Sample Rate Light (Red)… blinking.
3. When Power Switch is clicked to Off position, no lights whatsoever.
= No audio output via headphones ports or RCA outputs.
Has my unit gone to Hugo heaven?
It's not your battery life light that's blinking red (that's what should blink red on low battery)? Sample frequency light should not blink red unless it's the light bleeding over from the battery life light. Vol green is correct when you power on, and input light is white, also correct.
Also, when you turn off power switch, there of course would not be any audio or RCA output because it is turned off. The battery charge light should, however, remain lit (white) indicating it is charging. If charging light is not on, it could possibly be a defective power adapter.
