Procedure to get sound working in Fedora 22 on ASUS C300 Chromebook

This will probably work with other distro’s/Baytrail Chromebook models.

  1. Get to a terminal.
  2. Type “alsamixer”.
  3. Press the brightness down key AKA F6.
  4. Find “Left Speaker Mixer Left DAC” and press “m” to unmute.
  5. Find “Right Speaker Mixer Right DAC” and press “m” to unmute.
  6. Update your distro to hopefully as new a kernel as possible (mine went to 4.1.4-200). This ensures that the sound card has the latest available firmware.
  7. Reboot.
  8. Enjoy shiny (and possibly slightly dodgy) sound.
