What TDM audio CODEC can I use?

I see in the documenation (https://docs.espressif.com/projects/esp ... s/i2s.html) that the ESP32-S3 has TDM audio support. However, it says, "due to the hardware limitation, only up to 4 slots are supported while the slot is set to 32 bit-width, and 8 slots for 16 bit-width, 16 slots for 8 bit-width." This is 128 bit clocks in one frame, which I have not encountered before. Every CODEC that I know of uses a 256 bit frame with 8 slots of 32 bits, even though they generally use fewer than 32 bits per sample.
Does anyone know of an audio CODEC or a DAC with 8 channels out that can use 16-bit slots?
