Hey, I own a Notebook 7 and was having the same problem with the headphone jack (sound very low and distorted). I managed to solve based on the solution at https://bbs.archlinux.org/viewtopic.php?pid=1898849#p1898849. Basicaly, I created the files at /lib/firmware/alc256-sound-patch.fw with the content
[codec] 0x10ec0256 0x144dc824 0 [verb] 0x1a 0x707 0x05 and at /etc/modprobe.d/alc256-sound-patch.conf with content options snd-hda-intel patch=alc256-sound-patch.fw Reboot, and you should have sound working even after reboots. The values may differ in the codec line, but it's all explained at the link I put. You may test before applying the patch with the command sudo hda-verb /dev/snd/hwC0D0 0x1a 0x707 0x05 (the sound must be playing and headphones connected, but it will no persist after reboot) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850702 Title: [Samsung Notebook 7 Pro, Realtek ALC256, headphone jack] Headphone sound is faint and distorted (but works fine in Windows) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1850702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
