Roon Arc upsamples to 48khz on iPhone?

Hi guys!
I absolutely love the Arc feature. I’ve been waiting for it since 2017! Kudos, devs.

Quick question though: can anyone explain to me why all my flac files are upsampled to 48khz on iOs? I only have the green dot, not the purple one.

Is there a way to avoid that ?
Thanks !

The limitations of the audio output of iOs I’m afraid. You’ll need a USB dongle to bypass this limitation.
