Is it possible to perform AC3 passthrough on HDMI ??

[subodh]

Hi,

I ma using IMX 6Q SABRE SD. I donot have a SPIDF header on the dev board.

I want to play an ac3 file on HDMI Monitor.

Is the above use case valid ?

If so, how to accomplish the same.

I do not intend to decode the AC3 in software on board.

I tested this sometime ago on a mx6 board and it worked fine:

ac3dec -D hw:1,0 -C test.ac3

-The -C option tells the application to stream AC3 data

Following link allowed me to do aac playback

https://community.freescale.com/docs/DOC-93745

But I was unable to locate alsa tools under LTIB.

Am I missing something in configuration ?

[Yuri]

  LTIB distro does not contain alsa-tool package, therefore the only way
is to build it manually from sources. Perhaps it makes sense to port Your
applications to Yocto.

Have a great day,
Yuri

Hi Yuri,

I am new to embedded systems.

Is there any clear advantage of Yocto over LTIB when it comes to building new packages ?

[Yuri]

At least one clear advantage - all further updates will be supported by Freescale
only for Yocto.

Thanks for the guidance YuriMuhin_ng and FabioEstevam.

I will first setup yocto and then take up the alsa-tools issue.

Subodh,

If you are starting with embedded systems, I would suggest starting with Yocto, as there is a very active community of developers.
