Status changed to 'Confirmed' because the bug affects multiple users.

did the driver still waiting for grpahic driver to provide a valid ELD or lost ELD after suspend/resume ?

I posted a bug upstream: https://bugzilla.kernel.org/show_bug.cgi?id=74861

[Peter Curtis (pdcurtis)]

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.

Marked as fixed release for System76 as the 14.04.5 release of the system76-driver includes a grub line fix for this:

[David (rudder2)]

I can confirm that after hours of serching the internet and trying fixes that passing i915.disable_power_well=0 on the kernel command line works around the problem, letting audio play at the correct speed again.

I'm running a Shuttle SZ87R6 with Intel Core i7-4770K Intel Z87 Chipset using on board video and audio. The HDMI and Optical out is going to a Pioneer Suround Sound System before the HDMI continues on to my projector.

The S/PDIF works perfectly all the time but only has 2 channel audio which is annoying so I wanted to use the HDMI of course.

I'm running KUbuntu 14.04 Trusty.
