So these are things I noticed so far with my Q5S.
1) There is a volume difference in Bluetooth (LDAC) and USB audio, not sure why it is, I kept my phone volume to 100% and Q5S volume constant in both cases, but still Bluetooth is about 20%-30% louder than USB.
2) This is bit more serious I am hearing some clicking / popping / hissing sound in USB mode, this particularly occurs when the song is paused (so it should be quiet), changing the input and turning the amp on / off using the volume knob, I am scratching my head because Bluetooth mode is absolutely quiet.
3) I used the Ampere app and its showing a reading of ~500 mA in USB mode, wth no USB it's about 160 to 200 mA, the measurement for Q5 using proper OTG cable (non charging data only) is only about 200 mA, youtube link here.
Can it be a faulty USB module? I am using the official FiiO CL-06 cable for usb connection.
