CF-R9 : no sound ! (in windows/linux) + wiki

anybody made a triple boot (Windows, Linux, ChromeOS) on their machine ?
my R9 gets a little hot on Windows ... I need to check it more on my linux boot ... maybe try ChromeOS too ...

PS :
according to https://github.com/sebanc/brunch maybe triple boot with NeverWare CloudReady / FydeOS is safer than ChromeOS ?

PS2 :
most of the tools I see for dual booting ChromeOS/NeverWare CloudReady are mostly for UEFI Bios so the R9's legacy bios might be an issue ...

 

If you’re still having problems with sound,
Look at MxLinux website
There’s alit of information on sorting out the sound with AlsaMixer

thanks but I already sorted the sound issue by installing hotkey drivers and apps from https://askpc.panasonic.co.jp/s/download/install/r9kw.html#model2

I see MX linux has xfce and is quite light ... maybe I ll try it ... right now it looks like if I use Edge instead of Yandex browser on my R9 then it heats up a little less on Windows ... on linux I am using Yandex browser because it s the only browser I ve found that has a good implementation of the "top bars" auto-hide feature, but I can t comment yet on the heat produced as I haven t used linux (lubuntu 20.04 currently) long enough ...

 

Sound does not work on any linux distro on cf-c2 out of the box. You have to use pulse audio or alsa mixer to make the headphone unmuted while unplugged. You will have to do this every time you reboot.
I made a simple solution since this seems to affect the these and a few other models. Tested on Mint and Arch. Just find and edit the analog output speaker conf file.
Try the new mint that just got released

usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf and when the file opens
find this section:
CODE:SELECTALL
; This profile path is intended to control the speaker, let's mute headphones
; else there will be a spike when plugging in headphones
[Element Headphone]
switch = off
volume = off
Change it to this:

CODE:SELECTALL
; This profile path is intended to control the speaker, let's mute headphones
; else there will be a spike when plugging in headphones
[Element Headphone]
switch = mute
volume = merge
2. Save and close the file, ignore the terminal warnings and reboot.

 

I tried NeverWare CloudReady on an USB stick and it s working well not too much heat and performance is good about 12400 with octane v2 (Chrome under linux is about 11400 and Edge on windows is about the same if I remember ...)

The issue is that it won t auto-update ... and it can t be installed to another usb stick, only to main hardrive (which contains my Windows 10 & Linux setup ...)

 

wow apparently I should be able to triple-boot ChromeOS according to https://github.com/sebanc/brunch/issues/77 !
(or Successfully Dual Boot ChromeOs and Windows 10 in legacy BIOS / MBR without installing Linux OS · Issue #705 · sebanc/brunch (github.com) )

(I initially thought there would be an issue with my legacy BIOS ...)

PS : Oh no : "Intel Gen 1 graphics do not work with ChromeOS versions above r81" according to sebanc/brunch: Boot ChromeOS on x86_64 PC (supports most Intel CPU/GPU or AMD Stoney Ridge) (github.com)
