Z5 Compact speaker volume dropping

[Voro]

Please can somebody help me? My Z5 compact while receiveing a call has very loud ringtone volume only for about 1 second, than it drops by around 60%... The same issue occurs while listening to music on speakers, it is loud for 1 second than volume drops... It is not caused by any setting I think. Please help

I was having similar issue but it was about speaker mode during making the calls.. volume of speaker was very low on speaker mode, but later it just got back to normal itself.. And I got below information from Rickard on this forum again that some calibration in background goes on and sound gets back to normal after a while... may be your situation is related,

I've got some more information about this and when the loudspeaker volume decreases after about one second, this may be caused by “Smart amplifier calibration”, a Sony Mobile protection system for speaker playback to prevent damages to the speakers. The system needs a calibration when you reboot your device the first time. This is why the received voice on the speakerphone appears to be unstable. The calibration takes about 45 minutes. It runs automatically in the background and doesn't affect the audio for normal phone calls.

I my self experienced the same issue the very first time I bought the device and statarted using the native music app with sound settings untouched. I did 6 factory resets without any changes anf I was very frustrated because as soon as I open the app and listen its really loud then it drops and become softly quite and almost unbearable. Very annoying then i gave up. For some unknow reason it fixed it self and it was very loud again. Now with the new update rolling out ending . 200 i thought its better to do factory reset for clean instalation and I forgot about this issue now its been a day and still not fixed and I am bothered. I totally hope it fixes it self because it would be bad to spend another day doing factory data resets and reinstalling and configuring cuz its time consuming.

So do we need to play music for 45 mins straight or it is an automatic thing?

when I put it on speaker mode during a call, volume of the sound dramatically gets lower in 1 sec and it is not possible to hear from distance..
