Hyperion - LEDs not working

I’m having a similar problem as @waffi was having in this thread: Kodi with Ambilight -> leds stay off

Running an Odroid N2, with an Arduino connected via USB running adalight with WS2812 LEDs.
CoreElec 9.2.4.1 with hyperion NG 2.0.0-alpha.7

On the suggestion of @Portisch in that other thread, I have set the device output path to auto. I get the two brief flashes of my LEDs (which is part of the arduino code), but no matter what settings I use, I can’t seem to get the LEDs to do anything else.

The Arduino and LEDs work on other devices under HyperionNG, so it has to be something on the Odroid I’m doing wrong. The baud rate I’ve set matches what’s set on the Arduino.

Here is the output of my journalctl:
