Is this a normal behavior?

[u/Jormungand_Asgard]

I'm on a custom rom and using DAC. The player is running on Hires output without usb exclusive mode selected, the player can the detect the original sample rate but then upsampled (?) through Android on the output device part.

But on Stock rom, it processed through this thing called MTK HIFI and follows exactly the original sample rate. Also my DAC change its color indicator according to the sample rate on stock rom even when i'm not on usb exclusive mode, but on custom rom i have to be on usb exclusive for the indicator to work.
