    @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.

  • "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

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

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

    @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 .

    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.

  • 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.

  • 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.

  • 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...
