Subject: I2S frame configuration
Date: Mon, 08 Dec 2014 10:37:46 -0500	[thread overview]
Message-ID: <5485C5CA.8030402@gmail.com> (raw)

I am working on a ALSA interface to a particular codec over I2S

the audio stream format is a bit peculiar...  (CODEC being MASTER)

there are 24 BCLK cycle between transition of FSYNC...   howver, there 
are only 16 bit that are valid

bit 0: ignore
bit 1-16:   valid pcm data (MSB....LSB)
bit 17-23: ignore



Can anyone suggest how to configure the DAI format ???

Thanks
