My DAC doesn't make any sound.

cubacraft

Now I have sound but just with my python script allowing me to have music on the menu...

mitu

@cubacraft What does aplay -l list now ? Get the output and then play with the sound configuration in ES to match what the command says.

cubacraft

"aplay -l" return : "
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
Subdevices: 0/1
Subdevice #0: subdevice #0
"

Before the sound configuration menu, the raspberry return me this:
lv10: VolumeControl::init() - Failed to find mixer elements!
lv10: AudioManager Error - Unable to open SDL audio: ALSA: Couldn't open audio device: Device or resource busy

cubacraft

And "this sound device does not have any control" in AlsaMixer.

cubacraft

I changed the name of the audio device in the file "es_settings.cfg" but nothing happen.

mitu

@cubacraft From what I can see on the HifiBerry forums one problem might be that the mixer control is not properly detected - or rather is not the analog, but digital - by the Alsa lib and consequently by the SDL library which is used ES and most of the emulators.
You could try using the dmix Alsa mixer , explained in https://support.hifiberry.com/hc/en-us/articles/207397665-Mixing-different-audio-sources .

The name of the audio device can be set from the ES interface, you don't need to fiddle with the config file directly.

This tutorial doesn't work for me. dmix didn't change anything. I've tried different things but it doesn't work. I have to admit I'm starting to despair. However, I'm sure there's a way that my python program sounds great. I continue to search and hopefully find a solution.

cubacraft

Can this be a permission problem? I have to be a super user to run the command line sound tests otherwise it doesn't work.

pjft

I wouldn't change anything directly on es_settings.cfg but rather through the sound settings menu. Change the device and then restart EmulationStation and see if it works.

cubacraft

The sound settings don't change anything and when I use raspi_config settings to force to Auto, jack or HDMI, the raspberry answers me: "There was an error running option A4 Audio".

I'm going to post here the result of a few lines of commands, hoping that it will help to understand...
