ADAU1467 DSP Filter Coeffs

When writing DSP filter coefficients SigmaStudio writes the Slew each time a new filter co-efficient is written the the DSP. (for example when changing Eq setting).

When we send both coeffs and slew we get occasional corruption of audio (severe distortion).

Can we write the SLEW setting once after boot as set-and-forget and not send each time we change co-effs?

*Disappointingly my previous post has not been answered for two weeks so I'm trying to dilute it down to the most simple question in the hope that ADI will confirm it.
