Hi, I have an output of alexaPi as follows:

Jul 07 21:43:26 KloPi python[370]: INFO: Checking Internet Connection ... Jul 07 21:43:27 KloPi python[370]: INFO: Connection OK Jul 07 21:43:27 KloPi python[370]: INFO: AVS token: Requesting a new one Jul 07 21:43:28 KloPi python[370]: INFO: AVS token: Obtained successfully Jul 07 21:43:29 KloPi python[370]: [01e87270] alsa audio output error: cannot open ALSA device "default": Device or resource busy Jul 07 21:43:29 KloPi python[370]: [01e87270] core audio output error: Audio output failed Jul 07 21:43:29 KloPi python[370]: [01e87270] core audio output error: The audio device "default" could not be used: Jul 07 21:43:29 KloPi python[370]: Device or resource busy.

As is said i’m trying to run it on an headless PiZero without desktop and an Hifiberry MiniAmp and using it with Squeezlite. The Hifiberry Amp is the default audio output. Does squeezelite affect the audio output of AlexaPi? I’m unsure at the moment if i have to follow the Pulseaudio steps because i don’t use a desktop installation.

Hello, Alsa can’t handle multiples applications using a device at the same time. Try to :

• Use dmix PCM:

  output_device: "dmix"
  

  in /etc/opt/AlexaPi/config.yaml (You must also change device in Squeezlite)
• Use PulseAudio

I’m running PA on an old Raspberry Pi B that is less performant than a Pi Zero without any problem so I think you’ll not have any problem.

I am trying to install on jessie on a Raspberry Pi B. It cannot find vlc-bin. What to do?
