8.6.2 Voice filtering for playback at low sample rates
For playback the voice mode is enabled via DAC_VOICE_EN (Address 0x14, Table 56) where the
low frequency roll off is configured via control DAC_VOICE_F0 (Address 0x14, Table 56).
Note 7 Voice filter setting takes precedence over the 5 band-equaliser. If the voice filter is enabled for the
DAC signal the 5-band-equalizer for playback is automatically disabled.
