I implemented audo on the SAMA4D3 and D4:
./sama5d3x-ek/configs/nxplayer/defconfig:CONFIG_DRIVERS_AUDIO=y
./sama5d4-ek/configs/elf/defconfig:CONFIG_DRIVERS_AUDIO=y
./sama5d4-ek/configs/ipv6/defconfig:CONFIG_DRIVERS_AUDIO=y
./sama5d4-ek/configs/nsh/defconfig:CONFIG_DRIVERS_AUDIO=y
./sama5d4-ek/configs/nxwm/defconfig:CONFIG_DRIVERS_AUDIO=y
These, however, used I2S for interface to an WM8904 DAC.

Working through the remaining driver support I need for my custom board and I
can’t find anything related to audio for the sama5d2 devices (they have Class D
capability, with lots of modes).
Before I dive in and find some time to create a driver from scratch, have I
missed something? Documentation on audio support in general seems rather
lacking so any pointers in the right direction would be appreciated (even just
a suggestion of another processor with similar capability I can use as a
reference).
TIA,
Tim.
