Where can I get the sourcecode with audio for iMX233-OLinuXino-MINI-WiFi ?

[firawk]

I am newbie, please give me some help 

[JohnS]

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!

[JohnS]

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

John

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

[JohnS]

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

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:

https://www.olimex.com/forum/index.php?topic=704.0

https://www.olimex.com/forum/index.php?topic=4110

I didn't investigate it further i've the suspicion that the sound clock rate runs async to the sound file.

Oh, but the issue is not happened when i use Newest official Arch Linux image(https://www.olimex.com/wiki/images/6/6d/Imx233_kernel_2.6_ARCH_FS_WIFI_release_5.torrent)
