Hmmm
This is very strange because my A1 pro is very loud, of course if we compare to other phone not to Hi-Fi.
When you are on call you can adjust volume for receiver and when you are on loudspeaker you can adjust loudspeaker volume.
You can adjust volume settings in engineer mode.
Open calling dialer and type in
*#*#3646633#*#*
Then - hardware testing - audio - volume - voice - choose receiver and sound - change ul gain in NB, WB and SWB up to 252 and save.
