How to call the I2S driver for intel chipset in audio codec driver?

lyq811lyq811 Member Posts: 6

We are developping audio codec driver for an audio codec with I2S interface.
The platform is intel chipset with I2S interface. But we do not know how to call
the intel chipset's I2S driver in our audio codec driver.

I know Intel SST (Smart Sound Technology) driver expose an DDI interface
(GUID_INTEL_OFFLOAD_ENGINE_INTERFACE) for DSP offload engine, does it also
expose an interface for I2S? How can I call the I2S interfaces?

Audio Codec driver --------> Intel SST I2S driver (intcAudioBus.sys??)

Thank you very much in advance.

    You're going to have to go to Intel to get the documentation for their driver. It's not a standard device, so there's no standard model documentation.
