[Intel-gfx] Are there any recent i915 patchs that could possibly affect HDMI audio on BDW?

[Lin, Mengdong]

Hi ,

Are there any recent i915 patches that could possibly affect HDMI audio, during last two weeks?

We got an audio regression on BDW that HDMI audio output becomes intermittent. Maybe HSW also has the same issue.
It seems the HW DMA position is not correct and we suspect there maybe something wrong with audio data consuming on display side.

Any tips would be appreciated to further check this issue.

Thanks
Mengdong
