[Q] [Xperia GO] Message Notification Tone - Sony Xperia P, U, Sola, Go

It's been quite a while, but I didn't care so far. My notification tone stops working say after 2 hours after the reboot of my phone [works as soon as the phone is rebooted - for 2 hours!]. I tried setting a notification tone that's in the SD card, still it doesn't work. I have munjeni's custom ROM and as far as I remember, it never worked for more than two hours in my phone even before the ROM update. Is this is fixable?
Device: Xperia Go ST27i, Bootloader Unlocked, Rooted.
Thanks,
B.

The ROM update failed for me, I'm trying to do a software update for .154, let's hope for the best!

That's the problem. I can't get the .154 FTF from anywhere. I have another thread in this forum asking for one!

I experienced this problem just this month. on the 3rd and 4th time this happened, I somehow found out how the problem starts and how to solve it.
Usually, when I play music using my headphones, and at the same time I receive some text messages, the notification sounds and even the music cannot be heard(but audible through headphones).
I tried this unusual method, on the first time this problem occurred. Actually, I did it out of nowhere. On the second time, I did it accidentally again, but only after 2 hours when the problem occured. But in the 3rd and 4th time, I prepared for it. Here's how it works:
First, remove the back cover of your xperia go, exposing the speakers.
Then, gently tap the exposed speakers few times, 2-3 will do. tap the exposed speakers directly.
Put back the cover again. Put your phone on Normal mode (if it is on silent or vibrate mode), and check your notification sounds, e.g. lock sounds, music, message tone.
P.S. If ever this one worked on your xperia go, please post it on other forums and tell it to other people that are experiencing this problem.
Also, I only know how this happens and how to solve it. but I don't WHY this happens. Gotta notify Sony. thanks!
