Who knows how to repair low sound of speaker? I tryed to change speaker - problem remains. Is this hardware or software problem? Is some fields of eeprom or flash which are responsible for common sound?

It's a hardware problem. It seems that a few speakers are louder as others. All loudspeakers are dfferently.

You can make your loudspeaker louder, if you change the third byte of field 4111. Set it to 3F, then it is a little bit louder. It's not much, but you can hear it

Greetings, Marcus

I found it! The field 4111 really affects on sound when its value is 7F sound is much louder!
