hi,i read this thread to add a boot sound with cm11 base rom..
and problem was, as you write,that cm team hates boot sound so it's impossible to add it..
but there was some tricks,as example using /system/bin/stagefright command to start a boot sound creating a simple sh to add in init.d folder (stagefright -a -o powernon.mp3)..with last android 4.3 base seems that stagefright there was in /system/bin
But with my surprise in last cm base roms kk 4.4.2 8 (but also stock roms) stagefright command was deleted by /system/bin so it's impossible use this command to enable boot sound,and i don't know why was removed stagefright..Maybe now in KK roms there is another command that has substitued stagefright command?
PS the only system/bin command that i try to start a boot sound is "media dispatch play" that launch a media player automatically playing last song that you listen to..(try in terminal emulator)
teorically if you create a simple script with this command at boot should be playing last song..
you can try using an app boot shell (https://play.google.com/store/apps/d...lcommand&hl=it
but for me don't work
if you want you can search on Google some sh script (bootsnd.sh) or zip package (CM4DX-Bootsound.zip) where there is this trick..
Maybe someone can explain stagefright command on KK 4.4.2?
