As far as I know, the RPi5 tries to negotiate the max current with the power supply via PD (power delivery protocol). The internal pcb of the Argon ONE V3 can’t passthrough this information to the RPi5, because its a sink by it’s self. The IC (RP2040) at the case pcb doesn’t supports/simulate the PD negotiation between the pcb and the RPi5, so it’s needed to force the RPi5 to know that your power supply can deliver 5000mA.
Please ensure, that you have a sufficient power supply (27W). Some peoples seems to have tried to used the “old” one from RPi4, which is not sufficient.
Please check your bootloader config / EEPROM, if there is this entry:
PSU_MAX_CURRENT=5000
and in your config.txt
usb_max_current_enable=1
For your BLSTR DAC I think you must add this line too:
dtoverlay=hifiberry-dacplus,slave
like described at page 14 of the case manual.
For LibreELEC you shouldn’t use the argon1.sh script. There exists a Addon (ArgonRemote.zip) from Argon40, but this is currently a outdated version 0.0.1 (doesn’t supports newer than LE 9). Please give the updated version 0.0.13 a try.
