Why is my Android phone disallowing me from changing ringtone or notification sound?

 
OBSERVATION: It allows me to change it, but after a while, it’ll revert back to a particular ringtone, notification sound, or “Unknown ringtone”. No matter which sound I picked, be it from internal storage or SD, it’ll always revert back after a while. It’s like the ringtone is stuck!

SOLUTION: Some profile changing app that you’ve previously set up could be messing with the sound settings in the background, e.g. Llama, Tasker, etc. Check your triggers and actions for these apps, or just disable them completely for a while. See if the problem comes back. If not, bingo, you’ve found the culprit.

[shell]/usr/bin/amixer -c 0 sset ‘Auto-Mute Mode’ ‘Line Out+Speaker'[/shell]

Just make sure “Auto-Mute Mode” is not set to “Disabled”.

How to create MBR for booting into Windows

I had a dual-booting laptop with Linux Mint and Windows XP on it. After deleting the Linux Mint partitions, it failed to boot into XP because grub can no longer find the MBR. This was the error message:

error: no such partition
grub rescue>

Solution:

Boot into SystemRescueCD and run this command to create a new MBR:

lilo -M /dev/sda mbr

Note: My XP resides in /dev/sda.
