Is HDMI 24-bit audio is supported by i.MX6SDL Linux BSP?

Question asked by Satoshi Shimoda on Apr 19, 2015

Hi community,


Our partner want to know what format i.MX6SDL Linux BSP support for HDMI audio?

I checked chapter for HDMI driver in Linux reference manual of some revision (L3.0.35, L3.10.17, L3.10.53, and L3.14.28), and there is no description about 24 bits audio in these reference manuals even though there is the description about 16 bits audio.

And in source codes (imx-hdmi-dma.c) of these revision, 24 bits audio seems to be not supported.

So I believe 24 bits format by software, is this correct?


Best Regards,
