I am using the Si4684 with firmware rev 26 (DAB 5.0.5).
In the datasheet it states the feature
* Concurrent I2S / L-R stereo audio out
However, this doesn't appear to be the case, I can have either L-R or I2S but not both.
My I2S is configures as MASTER, 48kHz.
If I set PIN_CONFIG_ENABLE to 0x8002, then I get I2S output OK.
If I set PIN_CONFIG_ENABLE to 0x8001, then I get L-R output OK
but If I set PIN_CONFIG_ENABLE to 0x8003, then I only get L-R and No I2S DOUT (it is low).
Note that FS and CLK are working with 0x8003 setting.
(I'm rebooting between changes - so it is not that there isn't a tune to set up the settings).
I've also tried in I2S SLAVE mode, and the same is true, DOUT only works with PIN_CONFIG_ENABLE set to 0x8002.
Anybody got concurrent I2S and L-R with Si4684 ? or have any ideas why I'm not !

Thank you, No I don't really need both at the same time, but the datasheet suggests that you can, and I wondered whether I was missing the trick.
