Hi, i’m using version 3.512 volumio on a rpi 4 with screen, USB DAC iFi Zen Dac V2. Updated to latest version.
DAC displays white, wich is NOT DSD256 (it must be red)

See the difference: DSD128 is altset 4 wich is SPECIAL DSD_U32_BE
DSD256 is altset 1 wich is S32_LE (must be altset 4) at 192kHz but not DSD
In the previous volumio version i had no problem, the DAC turns red on DSD256.
Plz can you guys check this out?
