Bug Description

Ubuntu Release : ubuntu 20.04 LTS release 20.04
Driver : alsa-base : 1.0.25+dfsg-0ubuntu5

On Galaxy Book Ion (model NP950XCJ-X01, from 2020)
The audio device (AKG Stereo Speakers) is detected as : sof-hda-dsp
Profile : Play HiFi quality music

But I get no sound either from the speakers of headphone jack.
Guessing a driver issue, hardware not properly detected.

Note : Laptop was provided with windows10, sound is ok on windows (so it's not an hardware issue).

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.
