I've looked everywhere and can't solve this problem. I'm really new to advanced computer stuff and linux. I don't know what to include so just ask and I'll include it. I'm running ubuntu 18.04 on a CB3-111 acer Chromebook. In settings the only audio option is HDMI and it doesn't work. Originally there was only dummy audio as an option but I followed a tutorial that brought up HDMI as an option. I couldn't find the tutorial again but it only fixed the HDMI. I want to use internal audio and headphones but neither work. This is the return from the terminal command: 

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller (rev 0e)

and:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: Generic Digital [Generic Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: chtmax98090 [chtmax98090], device 0: Audio (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: chtmax98090 [chtmax98090], device 1: Deep-Buffer Audio (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Thanks for the help
