It uses I2S for sending / receiving audio. However, the master clock on our sound card is generated by the ADC, which supports only 24 bit data, so getting other sample formats is not possible.
The I2S sample format need not be the same as what the DMA controller reads/writes from/to memory.
A question on 'plug' - it accepts 'nearest' as the argument for format, rate, what happens in case the slave pcm stream supports the exact same format as requested by user software?
The plug plugin instantiates the actual conversion plugins only as needed; with no conversion, it vanishes entirely.
