Hi there,
I’m new to Lubuntu but not to Linux. I’ve been using Mint on another device for a year now.
I just recently installed Lubuntu in place of ChromeOS on my Samsung Chromebook 3 (aka CELES). It works well except for one major issue - no sound from built-in speakers or headphone jack, only the HDMI port. The internal mic is also missing. Opening PulseAudio Sound Control shows only Dummy Output and Dummy Input controls when HDMI is not plugged in.
I’ve been reading support forums and rolling through sound troubleshooting guides for a few days now with zero luck. Fixes often involve changing settings through alsamixer or pavucontrol, but both of these run into the same problem - the only audio port available are the HDMI (and there are seven different HDMI profiles for some reason?). pavucontrol offers the same profiles, except that “None” is an option.
This is what alsamixer looks like:
In searching your forums, I did find this topic, which seems to be exactly the same issue, but no working solution was given. Any new ideas here?
I should probably confess I ignored a lot of warnings about my model, CELES, being notorious for not handling Linux well. But this issue, albeit annoying, doesn’t seem like something that should be impossible to fix.
I should also point out sound worked perfectly when I tried GalliumOS.
