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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1886493 Title: Galaxy Book Ion, sof-hda-dsp detected but no soound (ubuntu 20.04) Status in alsa-driver package in Ubuntu: New 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). Thanks.
