No sound via HDMI - 64 Bit PC.

noelburke82

Hi there,

I am unable to output sound on my 64 bit Recalbox machines via the HDMI port.

For whatever reason, the audio seems to only come out of the internal speaker.

I have tried editing the recalbox.conf and forcing HDMI output, but this does not change anything.

Any ideas?

@noelburke82 batocera is still young. such configuration are not yet supported.

Same here no sound via hdmi, shows 4 hdmi output options when I only have one port, and also the volume goes to 0 everytime I set it and exit the settings. Sound only works on integrated 3.5 mm jack on main board of my pc. Must also restart for changes to take effect. (Running on Gateway GT 5012 pc with upgraded 3gb ram an old geforce video card with hdmi and pentium d 950 cpu) Also batocera.linux will not boot on my pc no matter what is changed in bios, for this I used a live PLOP boot cd and selected usb. Very excited about this project really awesome stuff

I bought a motherboard E35M1-M with HDMI, but I can not make it work the audio in the hdmi or vga usb and also the internal video card 6310 also does not recognize, only recognizes normal video of the board !? How can I recognize audio on HDMI and run 6310 video? Is there somewhere I can put audio to reconheser on the RECALBOX PC?

hi.
there are still known issue about the audio.
while i've no pc having the issue it's a bit tricky for me to investigate for the moment.

I have the same problem with hdmi and with jack 3.5, any idea what it may be? Will the nvidia graphics card?

That's funny, because for me is exactly the opposite. I've got sound through HDMI but doesn't trough internal speakers. I am using a Lenovo laptop plugged in a TV. Perhaps this could be a clue.. .

I have the same problem, Im running Batocera on an intel NUC i34010u i get no option under the sound settings OUTPUT DEVICE i just see my internal Audio Device and my USB Headphones which both work,

nadenislamarre

in fact, linux takes the default output, so, depending on the computer, its not the same.
and batocera is lacking a way to change it.

Whats weird sometimes i see the hdmi in the output devices others i don't. I have to sometimes reboot 1 or 2 times to get the hdmi to appear then set it again. ill keep trying to find out why.

Em meu notebook dell vostro 5470, o batocera fica sem som. Caso eu conecto minha TV LG e reinicio o sistema, permanece sem som. Porem ao acessar as configurações de audio aparece: AUTO, CUSTOM, HDMI, HDMI, HDMI, ALC290, com a TV conectada eu seleciono HDMI e abro uma rom, imediatamente o som começa a funcionar, porem o menu do Batocera ainda permanece sem som, após reiniciar o Batocera, consigo ter som normalmente em minha TV tanto no menu do Batocera, quanto nos jogos.

Meus únicos problemas no momento é conseguir fazer funcionar o som no ALC290 para que eu não precise utilizar minha TV para jogar e, a imagem que tenho em minha TV, pois fica cortada. 🙁

Bonjour,
comme beaucoup de monde j'ai un problème avec l'audio HDMI sur une RADEON 5770
j'ai cherché un peu partout et j'ai trouvé un truc qui 'fonctionne' en partie

c'est:

Eu consegui fazer a minha funcionar da seguinte forma:
1 - No terminal, ctrl + alt + f2 ( pra mim não funcionou via Putty ou similar, somente no terminal do computador com Batocera)

2 - mount -o remount,rw /

3 - digite alsamixer. Na tela que abrir veja se possui a opção master e ela deve estar com MM, vá com as setas direcionais do teclado até ela e pressione a tecla m que vai sair de MM para 00. Depois pressione S e na telinha que abrir escolha outra opção de saída de audio e dê enter, deve ficar com apenas a opção S/PDIF, faça o mesmo procedimento com a tecla m, neste momento vc já deve ouvir o som sendo produzido. Saia do alsamixer com o esc.

4 - Crie um diretório para salvar a conf do alsa.
mkdir /var/lib/alsamixer

5 - salvar a conf do alsamixer
alsactl store

6- Salvar o overlay do recalbox
/recalbox/scripts/recalbox-save-overlay.sh

au moment de l'étape 3, le son revient, donc je continue
tout fonctionne sauf à l'étape 5 forcement la sauvegarde
alsactl store
alsactl: save_state:1626: Cannot open /var/lib/alsa/asound.state for writing: No such file or directory

donc le chemin doit être différent sur la version 5.9

quelqu'un aurait-il la solution svp ?

Bonjour gadjet203

Tu as essayé de créer le fichier en lecture/écrite pour tous ?

touch /var/lib/alsa/asound.state
chmod 777 /var/lib/alsa/asound.state

nadenislamarre

does
alsactl --file ~/.config/asound.state store
help ?

/var is a temporary directory on batocera. lost when shutting down.

alsactl --file ~/.config/asound.state restore

By using gadjet203 tip I've found a way to activate HDMI sound on my Nvidia card but a restart reset my actions...
Here what I do:
On menu I force sound on HDMI1 then I restart
After the restart I go to command line with F4 then Alt+F2 and root login
I enter "alsamixer"

This is the HDMI sound and the MM indicate that it's off, to turn on push "M" on your keyboard:

When they are at 00 it's activate.
Then push "S" and select your motherboard card and press enter:

You will see the master at zero, with your arrow select it and increase the volume with the up arrow:

To finish deactivate the rest with "M" button then press escape.
enter "startx" to go back to Batocera and sound is back

I've tried to use:
alsactl --file ~/.config/asound.state store
And also:
mount -o remount,rw /
mkdir /var/lib/alsa
alsactl store
/recalbox/scripts/recalbox-save-overlay.sh

But when I restart, the sound is off again.

Cocolas44 You need to load the stored configuration with /etc/init.d/S99custom, otherwise everything gets lost upon reboot. See this guide: https://batocera-linux.xorhub.com/forum/d/794-how-to-hdmi-sound-on-x86-builds

Hi,
Just for the info I have the same problem but on the same PC I have installed openElec and now libreElec and I never had any HDMI audio issue.
