OS: Roon ARC, Android
Source device: Samsung S25 Ultra
USB DAC: Khadas Tea Pro, Questyle M15
Issue: Android resampling everything to 48kHz
In my Roon ARC adventure I have been using USB DACs with my phone Samsung S25 Ultra.
Recently I have switched to Khadas Tea Pro, that I’m currently reviewing. Sadly, the ARC’s USB driver is not working properly with that device. I have spent considerable time with Samsung’s tech support, trying to make it work. Apparently, it’s the Tea Pro’s fault for not introducing itself properly to the Android system, which I passed down to the manufacturer.
But
UAPP has zero issues working with Khadas Tea Pro properly. It sees the DAC as it should and routes the audio outside of Android’s resampling engine. So it is possible to have a better USB driver.
Feature requested: more robust USB Audio driver, like the one used in UAPP. So it just works with everything.
