I asked the people you mentioned for the driver and as I understood from their answer, that this driver doesn't exist at least for free version of Arch. It's no problem, I would buy this 'uncatchable' driver if I would know where.
If I may, I would like to ask one more question:
Can the Rune output DoP through I2S? If so, why I can listen very noisy sound only from right channel during DSD playback and switch 'DSD enable' is on in Rune.
Thank you for your help.
P.S. Frank, did you mean this thread odroid-dac-ak4452-with-3-5-touch-display-t3990.html
if not, please, point me
