Batocera 32 X86X64 - No Sound HDMI

Mathsensey

Hello,

First of all, sorry for my English, but I’m French and I go through Google Translate to post this message ^^

I have a problem with the sound on Batocera, here is my configuration

- Batocera 32 X86X64 installed on the internal hard drive of my computer
- My computer is an HP 800 G5 Mini :
- LG television
- My computer is connected via HDMI to the TV

My problem is that I can’t get the sound to output to the TV, at best the sound comes out of the built-in speakers of the computer, in the worst case nothing happens.

- I tried all possible configurations between the Audio outputs and the Audio profiles, but nothing helped, sound on the PC speakers or no sound.
- I tried several HDMI sockets on the television, but nothing helped, sound from the PC speakers or no sound.
- I tested several different HDMI cables, but nothing helped, sound on the PC speakers or no sound.
- I tested via Kodi from Batocera, but nothing helped, sound on the PC speakers or no sound.

On the other hand, I installed Windows 10 on this same PC and the sound comes out well from the television without specific settings, I installed RetroArch from Windows 10 but I don’t have sound only in RetroArch or the sound comes out of the speakers from the pc but nothing from the television.

I think there must be a compatibility issue between my hardware and Batocera and / or Retroarch.

I tested different tips that I found on the forum but it doesn’t work.

I think the ultimate solution will be to put a pair of speakers on the jack of my computer, unfortunately I do not see other solutions :(

This might sound dumb, but have you made sure that your TV’s speakers are not muted?

Mathsensey

No no the sound is well mounted on my speakers, moreover under WIndows 10, I have no problem with the sound via the TV, only under Batocera (and Retroarch even under Windows 10)

Atari

Then could it be that you need to set a particular setting on your TV? I know for my one, it would not work until I set the sound type to “Bitstream”, it was on “PCM” previously. Something to do with the encoding of the signal?

Mathsensey

No I do not think that it is linked to that because even in the Audio outputs it does not find HDMI, I think of an incompatibility between Batocera and my equipment unfortunately. I plugged in a pair of speakers and the Audio output for the speakers appeared.

Atari

Hm, then maybe you are right. That’s unfortunate. You could always generate a support file and submit it as a formal issue, maybe one day it will get fixed that way.

Mathsensey

I finally found where the problem comes from, it is an incompatibility between Retroarch and my configuration (9th generation I5 processor, Intel HD 630).

The current version installed in Batocera does not yet contain the drivers to detect sound via HDMI.

I tested the stable version of Retroarch (version 1.10.1) and my audio output via HDMI is recognized.

So the only solution for the moment is to wait with the next Batocera update hoping that it will update Retroarch to version 1.10.1 minimum.

Otherwise, there is no immediate solution.

Here is my return.
