Gabriel Lemieux, as per http://support.hp.com/us-en/drivers/selfservice /HP-Spectre-13-4000-x360-Convertible-PC/7527520/model/7801792 an update to your computer's buggy and outdated BIOS is available (F.25). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, 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 For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags removed: bios-outdated-f.12 ** Tags added: bios-outdated-f.25 ** Summary changed: - Audio broken on HP Spectre x360, broadwell-U audio controller + [HP Spectre x360 - 13-4010ca] Audio broken, broadwell-U audio controller ** 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/1441852 Title: [HP Spectre x360 - 13-4010ca] Audio broken, broadwell-U audio controller Status in Linux: New Status in linux package in Ubuntu: Incomplete Status in linux package in Fedora: Unknown Bug description: On ubuntu trusty, Audio driver on HP Spectre x360 doesn't work.
