Moto G 2nd edition
I have had difficulty with this since moving on to marshmallow.
As I understand it the volume control only controls the ring tone volume
now. However when this button is pressed a media seik control is activated
is activated in the notification area. I have tried altering the media
volume and therefore the talkback volume using this control and
inadvertently muted the sound completely.
I have found that when an app like Tune In radio is loaded the volume
control does alter the talkback volume and so I have used this rather
long-winded method to avoid mistakes.
Is there a quicker but more reliable method for changing the media volume in
Marsh Mallow than loading a data program like Tune In.
