When I try to play a file with a 32bit float format via ARC, I just wait for the sizzling noise.
Android 13 phone. I’ve tried other Android phones, either I get a format error, or the same thing.
The same files transferred to the phone storage space are read without problem by the default music software.
I found the same with Roon locally - accidentally converted some files to 32-bit the other day, and Roon wouldn’t play them at all. Had to reduce the bit depth to 24 for it to work.
