No sound in loud speaker


I have a problem with my phone C6603, don't play any sounds on loud speaker.

I change a speaker and a flex cable and nothing, in earspekers i have a sound.

I change a mother board from other Xperia Z and sound works. Does anybody have a service manual or now how to repair this? It's definitly hardware problems, i flash every possible firmware and nothing change.

Sorry for bad English.

Try this solution i found on sonymobile forums, Put ur headphones to phone and play song. Pull headphones while song is running phone will pause the song now just play the song without headphones. It should play on phone speaker.

Apparently it's a radio app bug. Play radio. Force speaker output. Click apps list (square virtual button). Close radio.
