Doesn't fix the issue. Looks like audio driver uses stale value:

[ 2644.305055] broadwell_get_display_clock_speed 4c000000
[ 2644.305057] i915_audio_component_get_cdclk_freq 675000
[ 2644.322469] broadwell_get_display_clock_speed 4c000000
[ 2644.325669] broadwell_get_display_clock_speed 48000000</pre>
