Phone boots with sound off? Bug maybe....

[pank]

Strange thing is happening, when I reboot my phone (sound is on full blast before I shut off) it boots in silent mode??

Is there any reason this would happen? Did a factory reset (still happens) / I'm currently unlocked and rooted with no mods other than Nova launcher (same thing happens with default launcher). Also did a battery pull with no luck.

Any help would be greatly appreciated.
