From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Despite what I claimed in commit c3c5dc1d9224 ("drm/i915/audio: Do the vblank waits") the vblank interrupts are in fact not enabled yet when we do the audio enable sequence on VLV/CHV (all other platforms are fine). Reorder the enable sequence on VLV/CHV to match that of the other platforms so that the audio enable happens after the pipe has been enabled.
