Does Orin NX HDMI Audio support hot-plug?
Module: Orin NX 16GB
Carrier Board: Custom carrier board modify by p3509-a02.dts
What would be the test result of
Reboot the device with “no HDMI connected”.
Hotplug the HDMI with audio supported after system boots.
Will you see HDMI audio option?
Yes, I can see the HDMI audio option when hotplug the HDMI with audio supported after system boots.
Monitor A: does not have audio support
Monitor B: have audio support
Ok, so the issue here is if you hotplug A first and then B, the HDMI audio option will not appear. But if you directly hotplug B in the beginning, then it will work?
May I know which jetpack release you are using here?
The version is L4T 35.4.1
We will try to reproduce this issue locally.
This issue would be resolved in next rel-36 release.
