Ah, please test model=dell-headset3, it should work. And please also add options snd-hda-codec-realtek dyndbg, then boot the system without the headphone plugged.
after boot up, plug headphone, and test if it works well. If it works well, please upload the dmesg. thx. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851518 Title: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1851518/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
