I'm looking for a permanent way to permanently change the i2s_format  of your REF_AUDIO_MA12070P reference boards. I would use 4 of these boards in tandem with a MiniDSP USB streamer to create a speaker demonstrator solution which we would carry around.

The MiniDSP i2s_format is fixed to i2s standard while your REF_AUDIO_MA12070P board boots up in left justified mode. I managed to reconfigure the board trough I2C as documented in the manual but these settings are lost after  power cycle.

The REF_AUDIO_MA12070P reference board/ MA12070P device are factory programmed for left justified I2S audio.

It will always start up in left justified mode when power is applied.

It needs an external I2C command from either a host MCU or GUI interface to change modes, but the setting is lost when power is cycled.

Thanks.
