Aw yeah I didn't install any codec or SW to have this issue, but auto updates are activated. I guess I'll have to send it for tech repair as I have 1 more year of warranty..
I'm having the same problem.. what happened? It was working ok until 30 or 31st of July 樂... No audio incoming from the main speaker: I can't make any normal call; I have to use the lower speaker or headphones...
