Jérémie, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/inspiron-17-7737/drivers an update to your computer's buggy and outdated BIOS is available (A12). 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, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** This bug is no longer a duplicate of bug 1457446 No HDMI Audio Source on Newer Kernels ** Tags added: bios-outdated-a12 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Attachment removed: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458478/+attachment/4403946/+files/lspci-vnvn.log -- 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/1458478 Title: No HDMI audio output on newer kernel (3.19.0-18).
