I'm having the same issues albeit with a slightly different model HP Spectre x360 (13-4003dx).
Strangely enough, "/dev/mem: Operation not permitted" is the response I get even as root, (on the Ubuntu 15.04 livecd) using either of those commands. Simply using 'dmidecode' on its own gives me the following output: ----- # dmidecode 2.12 # SMBIOS entry point at 0xa9eeb010 /dev/mem: Operation not permitted ---- I'm attaching the output of lshw in the hopes that it will be useful. I'm also willing to try other suggestions that may help. ** Attachment added: "lshw.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1441852/+attachment/4394705/+files/lshw.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441852 Title: Audio broken on HP Spectre x360, broadwell-U audio controller To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1441852/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
