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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886493 Title: Galaxy Book Ion, sof-hda-dsp detected but no soound (ubuntu 20.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1886493/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
