Comment 49 for bug 1313904

@unrud, thanks for the work. I've extracted the files and just testing out init-headphone on my Arch Linux (Linux 3.19.2-1-ARCH #1 SMP PREEMPT Wed Mar 18 16:21:02 CET 2015 x86_64 GNU/Linux
)

I get the same issue as @Kiril

Can't find i2c bus. Make sure that all required modules are loaded.

Though I've not tried "acpi_enforce_resources=lax" as Arch Wiki actually said it's dangerous. I'll try it out when I'm free later tonight
