I recently installed franco.Kernel R15 on my stock OPO with TWRP and I noticed when I plugged in my headphones, there is a full second delay of it being detected (this was also present on R14). Is this normal? This occurred on several other kernels on my OPO as well such as stock Mahdi's, stock CM11 M9/nightlies, and so on. I've tested these combinations and are without the aforementioned problem, PA stock, Franco R13 on all the ROMs I've tested with (PA, DroidKang, Mahdi, CM11S), CM11S stock.
This issue is definitely related to the kernel and I have tried to flash the official recovery image and same results after flashing franco kernel R15. And I would inquire about this in his thread but as of now, I'm not eligible to do so.
Thanks for the help! Cheers!
