Hi, Callaudiod selects available profile with highest priority in voice call. It's 'Voice Call (Earpiece, Mic)'. When speaker is selected, callaudiod tries to change port in selected profile to 'speaker'. But 'Speaker' port isn't available in 'Voice Call (Earpiece, Mic)' profile. First profile has to be changed to 'Voice Call (Mic, Speaker)' and then 'speaker' port selected.
