Description of Issue

I’m trying to get a lossless signal to my Audize via iPhone which I know it’s possible but for some reason Roon insists on upsampling my 44.1kHz FLAC to 48kHz even with sample rate conversion disabled.

Am I doing something wrong?

Any help is appreciated, thank you!

How are you connecting the isine10 to your iphone?

I’m connecting it with the Audeze CIPHER cable.

I suspect the lightning chip in the cipher cable is the culprit, which resamples everything to 24bit / 48kHz.

Yes, I have exactly the same issue.

It does still sound great though so I gave up stressing about it.


Understood, thank you both!
