@draamses I am surprised to hear it doesn't work, at least manually, on the flex. I obviously don't work for samsung and don't know the hardware internal details, but there is nothing in the script that is known to be explicitly model specific. I am also just running a standard ubuntu kernel now with none of the previously discussed kernel modifications, and the headphone jack and the speakers work with the script. It used to work automatically with the deamon before the last pulse and alsa update in ubuntu, but now I have an issue with pulse starting properly at boot. It is a real mystery why the flex is different given that the flex and ion were released at the same time, that both appear to have the same alc 298 sound devices, and that the script works on the always (released a few years earlier). Possibly there are two separate issues on the flex and both have to be resolved. Do you have pavucontrol installed and if so, do you see "sof-hda-dsp speaker + headphones" in the list of output devices? If not, you may also need to run "pulseaudio --start" before running the script. Also, have you completed the step to turn off the auto idle for pulse? If not, if you run the script before you have sound playing, then pulse will break the sound when it puts the sound card to sleep. To turn off the pulse power saving just run "sudo gedit /etc/pulse/default.pa" and comment out (add the ###) the line that reads "load-module module-suspend-on-idle". And reboot of course. You can easily revert if needed but just removing the ###.

Relase of Ubuntu: 19.10 Expected outcome: Music plays on the internal speakers and headphones. Actual outcome: I can barely hear audio using headphones with volume turned up to 150%. Absolutely nothing comes out of the speakers. (The speakers sound great under Windows 10.)
