@John Hoff Darn. Let's try something else.
I submitted a kernel patch adding model=alc298-samsung-headphone (see attached). It exposes the quirk that fixed my Samsung Notebook 9 Pro as a "model" option that you can pass to snd_hda_intel. Give it a try: 1) Apply my patch to the linux kernel, compile, and run it. (Alternatively, wait until my patch lands in your favorite linux distribution's kernel binary and then upgrade.) 2) echo "options snd-hda-intel model=alc298-samsung-headphone" > /etc/modprobe.d/alsa-base.conf 3) Reboot I tested on my Samsung Notebook 9 Pro (NP930MBE-K04US) which runs Arch. The filename in step 2) might be different for Ubuntu. ** Patch added: "0001-ALSA-hda-realtek-Add-model-alc298-samsung-headphone.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1851518/+attachment/5402049/+files/0001-ALSA-hda-realtek-Add-model-alc298-samsung-headphone.patch -- 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/linux/+bug/1851518/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
