i.MX6SDL HDMI supported audio format.

[satoshishimoda]

Hi community,

I have a question about i.MX6SDL HDMI.

We want to confirm the audio format i.MX6SDL HDMI supports.

According to reference manual (IMX6SDLRM Rev.1), I understood i.MX6SDL HDMI supports the following format.

Sample rate: up to 192 kHz

L-PCM bit rate : 16, 24 bits

Then, how about L-PCM 20 bits?

Is it not supported by i.MX6SDL HDMI?

Best Regards,

Hi Satoshi

yes you are right. One will have to convert it to

supported (16, 24 bits) format.

Hi Igor,

I understood the hardware supported format.

Then, I want to know the software supported format by BSP also.

I checked 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 manual 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?
