hello I am running 16 core (used to be chrome os) and there is no speaker, microphone or headphone jack detection
Bluetooth and HDMI audio works fine but not speakers, microphone or headphone jack
the Chromebook that I am using is an HP model 11-2203TU
detected audio device is: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller (rev 0e)
In the meantime you could open alsamixer in terminal, Hit [F5] to show All channels, then post a screenshot. Normal suggestion would be: Unmute all channels you see and increase levels and see what effect that has. Also can try Disable "Auto-Mute". But from link I posted, that didn't have much effect there.
