Lars Pensjö, as per http://www.dell.com/support/drivers/us/en/19/Product/latitude-e6520 an update is available for your BIOS (A18). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-18 ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/1018555 Title: No audio in headphone Status in The Linux Kernel: Expired Status in “linux” package in Ubuntu: Incomplete Bug description: When I connect headphones, there is no sound in them.
