Default [Q]Kernel with SoundEnhancement for 290


I want to ask if theres a kernel without the wlan-problems for the newest firmware? I am using 290 now and want to switch to 136 but with DoomKernel 7 the phone vibrates permanently.

Is there any tutorial which is showing how to add sound-control to stock kernel, because this is what I am looking for? Didn`t find any tut for that.
