Low volume output on loudspeaker

[Stefan Mikulaj]

The loudspeaker is on very low volume during the call, is on full volume and still can barely hear anything. When playing music songs the sound output is great on Meizu Pro 5 via the speaker but not when calling on loudspeaker. This should be loooked at.

Meizu Pro 5, OTA-13 , stable, meizu-pd.en

I want to update this bug report.
After I decided to reset the device and erase all, now the volume output is as it should be.
So this worked, but it should not happened in the first place.

It's acctually a problem with the sound volume. Once you receive a call, you can't change the volume and it stays on pre-call set level. This is very annoying when you can't add or lower the volume. This is happenning on laudspeaker as well. Another related problem to this is the alarm volume. Also it has to be set the volume before it goes off, otherwise is too loud or low.
This volume problem should be sorted out. It's a mess. Why can't Ubuntu Touch has an option like e.g. Cyanogenmod, press the volum button up or down and a slider appears for each, either calls, alarms or notifications/sms/email with the volume level. And once set, it stays on that level.
Once in active call, the push of the volume button only changes the volume for calls and set it to this new level. Same for SMS/Mail and alarms.
Please fix this.

And after couple of days the sound volume is low again on loudspeaker.
What logs do you guys need and what command to run to get them and where to find them, please let me know and I will provide them.

I found out that when switching to loudspeaker during the call, I have to first decrease the sound volume and then increase the volume to make the loudspeaker to work properly. The volume bar changes just slightly while doing this, but the effect is huge. First I was trying to increase the volume but it did not increase the volume at all, then I tried to decrease and increase the sound volume and it works. So there is obviously a bug regarding the sound settings. Similar behaviour I noticed in normal phone call. I had to decrease the volume and then increase to actually increase the volume to my preference. This should be looked at.
