UPDATE – “It’s Alive! It talks!” Using some hints from https://forums.linuxmint.com/viewtopic.php?t=303867 I got the audio working. I’m also editing in a few hints. See the Sat Oct 19,2019 1:04 pm post for the step-by-step. Basically seemed to be a driver issue with this particular Chromebook model.
The Audio Fix
CAUTION [SEE ABOVE – Resolved with some research and work!] – I’m struggling to get the Audio I/O working. Some users are reporting that the Dell 3120 (Candy) Chromebook running GalliumOS ends up with the audio inoperative, and few say they have it working. I’ve undone the whole process and repeated with the same problem. Might be better to pick a different Chromebook in the end. More to follow! [Edited 08FEB2020]
With some help from Vic KC9NWB I’ve mostly prepared a very inexpensive laptop to run WSJT-X with my soon to be built Midnight Design Solutions Phaser FT8 transceiver Kit.
I started with a Dell 3120 Chromebook which was a scratch-n-dent sale item at Amazon’s Woot. With the larger memory Amazon usually gets $100 plus tax for one of these, but catching it on a short Woot offer saved about $30 in my case. So with taxing delivered I’ve added $71 to my FT8 Phaser project for a dedicated computer. At the time of my writing Amazon does have some on offer (again S&D/renewed) for the $75 range.
I followed the conversion to Linux Joshua Woehlke wrote up at https://joshuawoehlke.com/galliumos-dell-chromebook-3120/
Some notes: Backup the firmware to a separate flashdrive, and do make a set of backup media to restore ChromeOS just in case you have to revert to solve problems like I did. https://wiki.galliumos.org/Installing is also another good reference. You can make a new ChromeOS restoration media drive through the chrome browser app plug-in as well. But having the right stuff handy is helpful and saves time if you do have to go back.
