CarPlay switching audio modes
My iPhone will randomly switch between Audio mode and Voice mode.
This means that when driving, at a random point, the audio quality will switch from 'Audio' mode where all speakers and the EQ is balanced for sound, and 'Voice', where the EQ balances for better voice quality.
This switching is expected when receiving a phone call, but not at random times. I can't prompt this to happen, repeat it or predict it.
Are there any suggestions for stopping this from happening.
It occurs in two different cars, over two different phones (1 recovered from the other), at random times, via a USB connection.
So far I have tried unpairing the phone, on both bluetooth and via usb, pairing just one at a time, deleting the CarPlay settings on my phone and deleting my phone on the cars and redoing connecting all of them.
I've rebooted the phone and the car media player too.
The issue seems to follow the phone settings and model. (MQ6G2B/A)
