DingDing Posted July 21, 2021 Share Posted July 21, 2021 Hello, I'm currently using qudelix-5k dac with Samsung S21 (Android 11). And, I'm having issue with using dac on usb mode. Qudelix-5k works very well in usb dac mode(output device/Qudelix-5K USB DAC 96kHz) when I disconnect bluetooth connection with it.(Qudelix-5k supports both bluetooth mode & usb dac mode) The problem is, to change and apply specific setting for qudelix-5k, I need to run qudelix-5k android app and connect bluetooth. When I turn bluetooth on and connect dac with my phone. Poweramp automatically change output device to bluetooth headphone.(output device/qudelix-5k/LDAC 32bit 98kHz) I checked SmartThings-audio output in andoroid notification bar(I'm using korean language for my phone so the name could be different) and make sure audio output is set to headphone, also I checked Qudelix-5k app, conformed active state is usb audio mode. I tried to figure out a way to change bluetooth output to usb dac output but I could not. Is there a way to change output device? Link to comment Share on other sites More sharing options...
andrewilley Posted July 21, 2021 Share Posted July 21, 2021 If you turn Bluetooth on, and a device is already paired to the phone for stereo audio use, that device will become the default output mode. That's the way Android is designed. Andre Link to comment Share on other sites More sharing options...
maxmp Posted July 21, 2021 Share Posted July 21, 2021 Also, some firmwares, such as Samsungs, allow manual switching (usually via notification shade switcher), but this is out of reach for non-root/non-system apps. Link to comment Share on other sites More sharing options...
