Hello,
I can't listen music and FM Radio, because audio output don't work. I try factory reset, other sony headphones and reinstall firmware with PC Companion and don't work again. This problem appears last week, when sometimes the music stops suddenly, but i can play again, but today i plug my headphone and not work.
What to do? Service Repair?
Hi, could you try this please....Go to Settings - Apps - Smart Connect - Press Clear Data and restart phone
Don't work 
I contacted with support and i wait for answer, but i think, that this is hardware defect 
It does seems like a hardware issue.
Did you try clearing out the jack? Blow soft air into the jack there might be something stuck and try again. If it doesnt work, then try bringing and cotton slab that fits the jack and clear any dust or anything stuck in there that could be blocking the jack. Also, ensure that you are pushing the audio input inside the jack to the fullest, sometimes it does not go in all the way. Finally, did you try any other headphones? Your headphones could be the reason. If none of these work, then contact Sony.
Best of luck.
I tried, but didn't solve this problem.
I took to the warranty service. I'm very disappointed with the support in Bulgaria, because my job is related to my work and now I haven't smartphone for my job. I paid a lot of money for this smartphone and the support in Bulgaria didn't meet my expectations...
