What I2S DAC uses left justified format?

[Tim Curtis]

Very odd.

The hifiberry-dac overlay specifies pcm5102a codec

https://github.com/raspberrypi/linux/blo...erry_dac.c

According to pcm5102a sources S32_LE is a supported format

But obviously ALSA believes that the device only supports up to S24_LE. i don't recall exactly how to get ALSA to probe the device and report its capabilities but possible running the cmd below will show something.

Code:

speaker-test -h
