I am newbie, please give me some help  :D :D

Go to product page, follow links.

Or use a web search.

It will take time and effort.  A lot is available, if you try.

I have tried a lot, but sadly no support sound.
Please give me some sources address. thank you!

Are you trying to say that none of the software supports any audio?

John

Yes. That's exactly what I'm talking about.

Unless you post details (yes, details) of what you tried and what happened you make it hard for anyone to help.

John

I assume you're searching for the i.MX233 builtin audio driver. I ported the driver to compile with Linux Mainline 3.19 and higher. Here is the git repo (branch: sound):

I merge the patch to my buildroot(from https://github.com/xythobuz/camcorder-buildroot) for imx233, but it can't work.Could you tell me how to debug?
here is the log:

Sorry, this might be a know issues:

Take a look at the several sound threads here:
