[AudioI] Isolated Soundcard not working on Manjaro ARM, but Zero does

[Ted Rippert]

Thanks Matt.

Here are some dmesg outputs with search terms for a successful load of the Zero on Manjaro, Failed load of the Isolated on Manjaro and successful load of the Isolated on RasPi OS. The only change to /boot/config.txt on Manjaro is the dtoverlay line for the audio injector card.

Manjaro ZERO:
