https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200526 hesitatej@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hesitatej@gmail.com --- Comment #7 from hesitatej@gmail.com --- I have the similar problem on my Dell Latitude E6440, running a FreeBSD 10.1-RELEASE-p26. The built-in speaker works without any further configuration. Upon plugging in the headphone, the speaker will be muted automatically, but there is no sound (only a very low level static noise) coming through to the headphone. The original configuration of the GPIO pins set by the operating system (FreeBSD 10.1-RELEASE-p26) is hdaa1: <Realtek (0x0292) Audio Function Group> at nid 1 on hdacc1 hdaa1: Subsystem ID: 0x102805bd hdaa1: NumGPIO=5 NumGPO=0 NumGPI=0 GPIWake=0 GPIUnsol=1 hdaa1: GPIO0: disabled hdaa1: GPIO1: disabled hdaa1: GPIO2: disabled hdaa1: GPIO3: disabled hdaa1: GPIO4: disabled I have written a script to use sysctl(1) to change the runtime tunable "dev.hdaa.%d.gpio_config" into all possible (5^5=3125) GPIO pin-value combinations, but none was able to make the headphone work. -- You are receiving this mail because: You are the assignee for the bug.help
