Volume problem

[Guest fungy1129]

hi everyone, i am using a Asus Aries WM6, i tried to play mp3 files on my phone by media player, but the volume is really low, then i go to setting and set the volume limit to maximum (105 db) then turn the phone volume to maximum, but the outcome is same, very low volume but a little bit louder, but still not suitable for listening to music when you are in outdoor.

i just wonder is there any method to change the registry file or any windows file that could help, thx so much !
