[alsa-devel] Stream format conversion in SoC driver

Hi,

We are developing a soundcard for Raspberry Pi, you may find the current driver source code here: https://github.com/raspberrypi/linux/blob/rpi-4.4.y/sound/soc/bcm/pisound.c

The card natively supports 24 and 32 bit PCM streams at 48kHz, 96kHz and 192kHz, symmetric capture and playback.

Is it possible to have ALSA do the necessary format conversions for the PCM streams in natively unsupported formats to the closest natively supported format?

What would be required to enable it?

Thank you, Giedrius.
