Asus rog phone 5s audio volume is floating with amps.
Asus rog phone 5s 8/128 global version. I have problem with audio output changing mode between 1Vrms and 2Vrms with connected to amplifiers. This asus should have manual options for switching high impedance and low impedance mode for headphones. If it connected with any amplifier then phone with volume set about 50% changing output volume trying to set proper voltage mode. ZTE axon 7 had it manually and was fine for experienced users.
