@senya, There are lots of error logs in the dmesg: [31989.266951] snd_soc_skl: disagrees about version of symbol snd_hdac_ext_bus_link_power_down_all [31989.266953] snd_soc_skl: Unknown symbol snd_hdac_ext_bus_link_power_down_all (err -22) [31989.266966] snd_soc_skl: disagrees about version of symbol snd_hdac_bus_send_cmd [31989.266967] snd_soc_skl: Unknown symbol snd_hdac_bus_send_cmd (err -22) [31989.266971] snd_soc_skl: disagrees about version of symbol snd_hdac_bus_enter_link_reset [31989.266972] snd_soc_skl: Unknown symbol snd_hdac_bus_enter_link_reset (err -22) [31989.266974] snd_soc_skl: disagrees about version of symbol snd_hdac_bus_get_response [31989.266975] snd_soc_skl: Unknown symbol snd_hdac_bus_get_response (err -22)
Let us temporarily move the /lib/modules/4.4.0-36-generic/kernel/sound/soc to a place, e.g. $sudo mv /lib/modules/4.4.0-36-generic/kernel/sound/soc ~/;sudo reboot Then test if headphone detection works fine or not. And you can restore that folder to the original place anytime you want. If move the folder soc/ does not help to fix headphone detection problem, Please also generate alsa-info.txt, this time please generate two, one is generated without headphone plugged, and another is generated with headphone plugged. thx. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1447909 Title: external mic not detected on machines with alc256 codec Status in HWE Next: Fix Released Status in linux package in Ubuntu: Fix Released Bug description: This bug is used for tracking, please do not triage.
