NVIDIA Next Generation ION is the Graphics Chip.

That didn't go very well. I ended up with no sound at all, so I had to re-installed recalbox to get it back over the Analog port. I am going to leave it, since I already bought speakers. @Dekiste @ian57 thank you for your assistance. My best guess is that the ZBox I have probably has some different NVidia chip, and they drivers probably are not shipped with recalbox to support audio over HDMI.

@Dekiste Correct, I tried different options under Card 0 and 1. Do I need to reboot after each change? I was just saving them and hoping for sound?

@Dekiste Didn't have much luck. Ended up buying cheap speakers and plugged them into Audio Out.

@Dekiste I did try few options earlier from this thread. But I will give it another try but using all the possible combinations of card / device. I will report back next week.

Yep. Anything I can try here? I have /recalbox/share/system/recalbox.conf?

I don't have boot/config.txt

Here is what I see in /boot

I recently installed Recalbox on a USB Memory Card. It is running on a ZBox. I am able to launch games, and sound comes from the Jacks. But there is no Audio when connected to Samsung over HDMI Cable.

I have looked through earlier posts and tried everything, still no audio.

When using KODI, I get Audio, when I select HDMI 1.

When in Recalbox, I don't see HDMI 1, only HDMI 0.

Any help is appreciated.
