HDMI audio out

[adityahota]

Hi @smallssnow, have you had any luck with the HDMI audio? I too am able to see that the audio selector is set properly in IORegistryExplorer, but the output does not show up. Is this something that needs to be handled by WhateverGreen/AppleALC?

嗨，@smallssnow，您对HDMI音频有好运吗？ 我也能够看到在IORegistryExplorer中正确设置了音频选择器，但未显示输出。 这是WhateverGreen / AppleALC需要处理的吗？

I chose the hdmi audio option according to the settings of the weg, but there is no audio output. There is only one case where audio can be output, that is, the hdmi cable is used to connect the display before powering on. Close the lid quickly after pressing the power button. At this time, the hdmi controller output shows that the audio controller is registered at the position of 0x03. I haven't figured out the specific principle. At the same time, I manually registered the hdmi audio output in applealc, but it also has no effect. I hope my exploration can help you

我按照weg的设置选择了hdmi音频选项，但是并没有音频输出，只有一种情况可以输出音频，那就是开机前用hdmi线缆连接显示器。按下电源按钮后迅速合上盖子。此时会有hdmi控制器输出显示的是0x03的位置上有音频控制器注册。具体原理我并没有搞清楚，同时我在applealc中手动注册核显hdmi音频输出，但是同样没有效果，希望我的探索可以帮到你

That definitely does help. I am noticing the same thing. I am not sure how to approach the issue though. Perhaps this is something the WhateverGreen developers can look at?

To be honest, I am not very clear about the registration order of weg and applealc, these principles are being studied

Good news! You can try the oc boot at github.com/xxxzc, I found that his boot can hot plug the hdmi audio
