Yes. A few pages back it was reported that the DAC was not used in most apps after the oreo update, although the hifi symbol was being shown there was no perceptible change in sound quality with either it switched on or off.

Does the oreo update kills the DAC when not using UAPP? I use some streaming apps which are not supported by UAPP? I also use low impedance IEMs. Can someone who updated please confirm?
