Neil Shepperd was too modest to say he produced a quick workaround in https://bugzilla.kernel.org/show_bug.cgi?id=74861. This simple simple fix works for me on a Chillblast Defiant mini laptop which has Haswell/Optimus Architecture, Core i7 Processor and nVidia GTX 765M graphics running Mint 17 (equivalent to 14.04).
The quick fix is to pass i915.disable_power_well=0 on the kernel command line which works around the problem, letting audio play at the correct speed again. After confirmation one can modify /etc/default/grub to make it permanent. Hopefully the commit will soon be reversed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288004 Title: hdmi audio is sped up/high pitched[Gazelle Professional, Intel Haswell HDMI, Digital Out, HDMI] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/system76/+bug/1288004/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
