The Symphony Within!
[...] the Mirari board hold a Trion FPGA. This FPGA can be configured to act as various components, including the glue logic for peripherals. One such peripheral is an onboard sound Texas Instruments DAC. Connecting an FPGA to a sound DAC often involves a communication protocol called I2C (Inter-Integrated Circuit). I2C is a serial communication bus commonly used for connecting low-speed peripherals to a motherboard or microcontroller. While the FPGA could certainly be programmed to talk I2C, MorphOS itself needed a way to initiate and manage this communication. Just as the already present AHI audio driver and NVME driver, Harald took on the monumental task of writing the actual sound driver for the Mirari’s onboard audio. Frank provided the essential I2C component for MorphOS. This wasn’t a sound driver itself, but a lower-level library or module that allowed other parts of the operating system (like Harald’s sound driver) to send and receive data over an I2C bus. As a result we are able to produce a 1kHz tone using the onboard audio."

Mirari.audio v6.1
The first version of the onboard audio driver has been finalized and compiled by Harald. This means there is no need for an additional soundcard in the Mirari mainboard anymore to have sound when using the MorphOS operating system."
