Previously I installed Ubuntu 12.04 with windows 7 then I installed Ubuntu because my laptops speakers were working fine in ubuntu and were not playing sound in windows7 or some times they have a very low sound.
After removing Ubuntu speakers stopped working completely where as headphone kept giving me good sound.
Now I have re-installed Ubuntu and still problem persists.
If you are bored with default s pen sounds then this thread is for you.. just flash through recovery and change those boring sounds. These flashable zips will replace S pen attach/detach sound (sound 2). If you wanna replace sound 1 or sound 3 let me know. Also if you wanna add your own sounds then just post your sounds here I'll make a flashable zip.
