Audio not working in recalbox on PC

[Ristul]

Hi, I have installed a fresh install of the 7.0.1 version on a PC, everything seem to work except for the audio in recalbox and also when playing games.

The sound seem to work in kodi though, and I think it has to do with the driver.

In kodi, I have an option that is not present in recalbox, the name is "HDA Intel PCH, MEI Panasonic-TV on HDMI". When I pick this option in kodi, sound works within kodi.

My question is, does anyone know why this option is not available in recalbox and is there a way to force recalbox to use that audio output?

Thanks

@Ristul Have you tried opening the Emulationstation menu (pressing Start on the console selection screen) and accessing "audio settings" (or something like that)?

@Ristul Hi there! Yes, I have the same issue with the audio output. It worked fine with 6.1.1 but I still have no sound through HDMI in 7.0.0 and 7.0.1. All the system sounds and game music is played by Internal PC Speaker or Jack 3,5mm.

Now, I can't choose any working option. I have only 3 choices: HDA HDMI, HDA Analog and Default option.

I will try with kodi and check if its related with driver or emulation station.

Same here. No Sound on HDMI output on 7.0 for x86/64.
Only on the jack/audio of the PC

Was working great with 6.1

[Ristul]

@AxelR Yes, 6.1 worked fine with my PC, I'm starting to regret upgrading to the latest version. And I find no older versions to download.

I tried changing the audio from recalbox.conf file to the one that worked in kodi, but the settings reset when I boot the system. Very frustrating.

@Ristul The sound management has been completly rewriten and there is some side effects, in addition, PC world is hell with hardware detection. To try to help you can you run these command lines in a ssh session on your recalbox :

amixer -c 0 contents
amixer -c 0 contrôles

and retry with -c 1 and -c 2 and post the outputs here.

you can try to select you specific sound output with alsamixer too.

@ian57 I tried to do what you asked, the first command worked fine, but "contrôles" was not accepted as a valid command.

Here is what I got.
