I have been running Arrow ROM v10.0.0 with Perseus.Adonis-alpha14 kernel the past weeks and it works flawless, I hadn't any issue with my phone until now.
I don't think it has to do with a hardware issue because of the unplayable audio files but I wouldn't like to go for the wipe before attempting other solutions.
Last night I was chatting with a friend, he sent me a voice message a I wasn't able to play the voice message, I was in a bar so I didn't have sound on anyway. Next morning I realized that I couldn't hear any sound at all from my phone, not even with headphones or when calling. The phone doesn't recognize when I plug in the headphones. The weirdest thing is that I cannot play any sound file at all, neither a song or any other, power amp won't event start playing the song, it just won't let me.
