Re: CVS commit: src/sys/arch/arm/allwinner



Can you see what happens to audio output when the display is turend off in this way? I have a vague memory of trying something like this before..

Not sure I like this. Disabling TCON interferes with HDMI audio (and this is
why the code was the way that it was) and I'm not aware of any "blank screen
but keep audio active" mechanism for HDMI displays.

So you say we should also disable HDMI audio ?
Maybe we could add a callback in awin_hdmi.c to turn on/off HDMI completely ?

What about the attached patch then ?
it should allow hdmi audio to still work, while turning off the display.
It looks even better, my display goes to sleep immediately with this
patch, while with the previous one it did look for a signal on other
inputs for a few minutes before sleeping ...
