The cs42l43 has both a SPI master and an I2S interface, in some configurations 2 cs35l56 amplifiers are connected to these to provide bass speakers whilst the cs42l43's internal speaker drivers are used for the tweeters. Add UCM configuration for this type of system.

Can do.
For my information - "AMPL/R Speaker Volume" is digital or analog volume control?
It's a digital volume, although I guess technically its controlled by firmware in this case, so in the future it could be updated to actually control the analog volume, but I am not aware of any plans to do so.
Thanks, Charles
