Recording file have no voice

[Ravi Ojha]

In linphone app , i am able to record the call and see the files in the list , when try to play it , progress bar duration working with file time.
But there is no voice
If i export the file from document directory folder seen that its mkv file and its have voice in the vlc player.
So i am sure something have became changed thats why its not playing voice with player in the linphone.

Let me know if i can fix this one
Thanks
