Hi Takashi,

I have tested the patch and it fixes the issue. Tested on kernel 3.15.0-rc6

Do you think you can get this patch in 3.15? Or will it be 3.16?

I'll queue the patch below for 3.15.

thanks,

Takashi

The recent Intel H97/Z97 chipsets need the similar setups like other Intel chipsets for snooping, etc. Especially without snooping, the audio playback stutters or gets corrupted. This fix patch just adds the corresponding PCI ID entry with the proper flags.
