Hi,
I have an issue with HDMI without audio output, I have seen the Colibri T30 supports HDMI audio output.
But I have tried the kernel of the 2013 version to comment out “#define TEGRA_FB_VGA”, which is not working, so how to enable HDMI audio??
Your prompt reply would be greatly appreciated.
Please check this article - Audio (Linux) | Toradex Developer Center
Okay, I have taken some time to satisfy my purpose.
However, those documents are very messed up, and have no complete route map to check something. I combined this with Google search to support my work…
To be honest, I have finished my work. But I have worked on embedded Linux for about ten years, I have not seen messed up documents, jump to somewhere or jump back… It takes much time to retrieve useful information, even worse than sunxi (China Allwinner).
