Linux is fairly new for me and any other information I need to provide
can be given as long as I am told on how to retrieve it.
This system I am currently using is Dell Chromebook 11 (Candy MODEL) with 4
GB Ram and 16 GB of Har drive space. I am primarily using a Linux Distro such
as Ubuntu or other distros in the same family. (This one is Linux Lite)
Audio will play from USB connected devices or Bluetooth speakers/headphones.
Internal speakers do not work at this moment and give me Dummy Output. The
configuration file in puvucontrol gives me HDMI outputs or surround sound but
no option for the internal speakers.
I'm pretty sure my kernal driver is snd_hda-intel and tried loading different
drivers from the file in '/etc/modprobe.d/alsa-base.conf' but to no avail.
I'm not sure if this certain device cannot produce output from a linux distro
but I will be trying other resources. I've reinstalled Pulse audio, its base
and reinstalled Linux on this machine multiple times.
