I'm running on an Acer Chromebook 11. I flashed it with SeaBios and set up Ubuntu (as xubuntu w/ lxde) as the ONLY operating system. That is to say, I am NOT using chrubuntu. Ubuntu has a direct link to the hardware.
When I play any sound, I cannot hear it over plugged-in headphones or earbuds, or the speakers. If I go to the sound options, I can put sound over two HDMI ports, but neither option works, or detects a "plugged-in" state, although the HDMI can be plugged in and the computer only has one HDMI port.
The Chromebook I'm using has built-in speakers, but neither the speakers nor the headphone jack are ever detected by the operating system.
Here is my result from alsa-info.sh:
Help would be urgently appreciated as this computer is a birthday gift for a friend!
