[SOLVED] with new Rpi4b (fixed red led)

[DRONE7]

Hi Tim,
I'm having pi4, 8 gb ram. The following are the issues I encountered  after installing the moode 6.6.
(1) Pi 4 (8 GB) Ram won't boot if it is not connected to my TV via hdmi irregards on whether the Local UI display is turned on/off.
    Anyway to boot Moode player without having to connect it to my TV?

(2) I intended to output the audio signal from Moode player to Wadia DI122 via Usb cable but the USB Device Type was showing Nothing to select.
I managed to did it once having the Usb ouput displayed and connected but next day it was disconnected and displayed Nothing to select. I have rebooted it several times including changing the Usb but the problem still persists.

I'm not a technical guy, it appears to me the booting is triggering by the hdmi connection irregards the local ui display is on off. I have reported it under the other thread.

As for the usb devise output. Yesterday, I managed have it output via USB. But today, it showed nothing to select again. Its performance is not consistent. My dac detected the connection as it showed the highest bit rate but moode cannot output it.

A couple of things come to mind...

1) RPi4 firmware...is this updated ?

2) The symptoms would  indicate a power supply issue,  random connections etc. 
What is the power supply you are using for the RPi4 ? Do you have any other USB devices connected to the Pi ?
