I do not get any music through the fm transmitter. When I switch it on while some music is playing, there is no sound just no sound. So, I can say fm is working. If I switch off fm, the hizzing sound through radio comes.

Now, here comes the tricky part, if I stop music when fm is on, I get the beeping sound. So, the fm is working just that music is not passing through to the fm. This happens to both inbuilt music player and some player.

I think this happened, when I started fm with my headphone plugged in. somehow some config file probably got overwritten.

I do not want to reflash to fix this :-(.. so any pointers on how to fix this would be helpful.

well the solution was pretty simple :-)... I had my volume turned off it seems. I turned it up and it started giving me music over fm.

It still intrigues me how the sound was coming when the headphone was inserted.
