Comment 1 for bug 1886493

I have a galaxy book ion with ubuntu 20.04 and have exactly the same issue.

I have found that I can make the headset jack work if I issue this command :

sudo hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0x5

But it only lasts until the sound subsystem goes to sleep (i.e. no sound to play or changing sound sources).

I have found no viable way to make the speakers work. One forum I read said it was likely due to the AKG Smart Amp in these new Samsung devices.
