  • Most probably, you don't have sound enabled in your Poky kernel configuration. And what you have in your kernel configuration depends on your chosen MACHINE at least. Also, Poky comes in different versions so there is a quesion of what version do you use. – Roman Khimov Aug 14 '16 at 14:34

  • So, what is the MACHINE you're using for your builds? – Roman Khimov Aug 15 '16 at 18:36
  • Ubuntu linux 64 bit – Mohamed Okasha Aug 24 '16 at 22:40

    I mean `MACHINE` variable from your local.conf, what's in your local.conf? It very well might be that your kernel doesn't have `CONFIG_SOUND` enabled because your `MACHINE` doesn't have "sound" in its `MACHINE_FEATURES`. – Roman Khimov Aug 25 '16 at 05:44
  • i am sorry for late MACHINE = "raspberrypi" – Mohamed Okasha Sep 01 '16 at 20:30
  • Are you using [meta-raspberrypi](http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/?h=jethro) layer? That has a specific [kernel recipe](http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/recipes-kernel/linux?h=jethro) with specific config (straight from kernel git) and that config has `CONFIG_SOUND` enabled. What is the output of `bitbake -v virtual/kernel` in your case (you can add that and all the other info (versions, layers, `MACHINE`) into the question)? – Roman Khimov Sep 02 '16 at 06:03
