That's odd, test your phone 

settings > about phone > diagnostics > test

I've tested the phone.
In diagnostics the sound is evenly balanced.
in service menu *#*#7378423#*#* left channel is very quiet.

when plays the music with player it's loud but only for  1 second and after left channel plays very quiet,right channel is normal.
but it's only when the phone warms up.

This is so weird. 

hardware problems or what?

Hi @FullMetal

Welcome to the community.

I would recomend the software repair. 

Here's how to run the repair on PC Companion:

  1. Install and open PC Companion then select Support Zone.
  2. Phone Software Update.
  3. Start.
  4. Repair Phone
  5. Continue
  6. Accept data removal
  7. Next
  8. Wait for prepare
  9. Select Phone
  10. Follow the connection steps

And Bridge for Mac:

  1. Launch Bridge for MAC without the handset connected.
  2. On the Main Window select "Xperia > Repair Xperia Device".
  3. Ensure the phone is charged and select "Ok" in the following window.
  4. Select Continue on the following page.
  5. Wait until the initialising step is finished the continue as below.

6 . Select your model of phone from the list that appears

  1. Follow the connection steps that appear, ensuring that you are holding the relevant button down before during and after the connection phase until the update/repair begins.

You will want to start these processes with the phone powered off and disconnected from the PC.
