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. -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to alsa-driver in Ubuntu.
