Hello! Having continued issues with this usb dac. Manjaro switches to the device automatically and makes it the preferred audio device upon it's recognition, however playing anything through it for more than 15 seconds causes the media to stop, buffer, and then Manjaro switches the audio back to my internal speakers, kicking the sdac out of 'audio devices' entirely. Unplugging and re-plugging in the dac makes it visible again, but still not usable.
Here's my inxi -Fxzc0 (without device plugged in)

Many thanks in advance! Also accepting any audio/sound tips for Manjaro in general, as I am new here and am somewhat audiophillic.
