when plug/uplug in front audio panel the headpones, this is not detect by ACPI, for this, the sound get in both output (headphones in front panel and in 5.1 speakers in backplane my setup)) in same time

downgrade to Linux-3.13-5 solve the problem (need downgrade to older gcc 4.8 due version kernel/gcc-libs version missmatch). tested with all kernels 3.14.x, all affected by this regression

'acpi_listen' can detect plug/unplug MIC in same front panel, and all jacks in mobo backpanel works. only fail the Headphone jack


Mobo: Gigabyte GA-EX58-UD5
integrated sound: HDA Intel ALC889A


linux-3.13-5 and older: works
linux-3.14.x and newer (latest 3.14.2): fail

This task depends upon

You need to bisect the issue and contact upstream developers.
