I use my Zenfone a lot to stream music (spotify) connected to several bluetooth devices (car, earphones, stereo setup, etc) and I have noticed that from time to time the audio quality starts to sound "muffled" (low treble). Every time this happens I have to go to audiowizard and even though I find settings intact, I have to slightly "touch" the treble slider in order to restore the normal audio quality, despite leaving everything exactly as it was before.
I have no idea why this happens or what triggers the symptom but for someone that spends hours listening to music, this can become really annoying.
Phone is running latest update (stable) of Android 12. Does anyone experience the same issue?
