HDMi sound speed reduced : Intel GPU

[Michel-Ekimia]

Since 16.04 on my Broadwell Low power Intel Mini PC, the sound ( and video) is playing really low speed which change any sound played on the PC.

TO overcome that I need to use the i915.disable_power_well=0 grub switch.

I woud be great to have this work as default.

the problem reappear after the machine goes out of sleep
