No sound over HDMI.

[abuzaid]

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.

@abuzaid hi there,

did you try :

hdmi_mode=2

in /boot/config.txt file

[abuzaid]

I don't have boot/config.txt

Here is what I see in /boot

[ian57]

@abuzaid arfff... you are on x86 :), the command is for Raspberry

[abuzaid]

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

Hello @abuzaid ,

try this:

it worked for me.

Regards.

@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.

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

@abuzaid what did you do? it worked for me making these steps:

-ssh connection (user: root, password: recalboxroot) and type the following:

mount -o remount, rw /
nano /etc/asound.conf

-Inside the file "asound.conf" write the following:

pcm.!default {
type hw
card 0
device 3
}

-After that, Ctrl+O to save the file and Ctrl+X to exit

If this does not work, try another device numbers, like 1, 2, 5...

Regards.

@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]

@abuzaid Yes, you should reboot the system after every change...

[abuzaid]

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.

NVIDIA Next Generation ION is the Graphics Chip.
