I'm using wi-1000x with xperia xz1c.
The audio configuration notification which says the headset is connected through LDAC sometimes does not appear when I pair my headset, or does not disappear when I unpair my headset.
The play button on my headset also sometimes does not work, not always.
The headset actually pairs, so I can hear my music, but the bug above is very annoying.
This bug does not appear when I use my headset with other phones, so it's definitely software bug of xperia xz1c.
