I have been trying to get ALC298 working for a while now and wanted to share my findings. This issue exist on all distros and is an ALSA problem (not pulseaudio). Verified it when found a fix for the headphone by using the kernel's early patching feature. To use this feature, write a simple patch (instructions here https://www.kernel.org/doc/html/v5.0/sound/hd-audio/notes.html):
[codec] 0x10ec0298 0x144dc169 0 [model] auto [verb] 0x1a 0x707 0xc5 and save it as /lib/firmware/alc298-sound-patch.fw then save: options snd-hda-intel patch=alc298-sound-patch.fw,alc298-sound- patch.fw,alc298-sound-patch.fw,alc298-sound-patch.fw to /etc/modprobe.d/alc298-sound-patch.conf Then reboot the machine and try your headphones. Next speakers! unfortunately all three mixer pins in the hda codec are set to mute and I'm working like a maniac to find a way of unmuting them, hoping that would fix the speakers. Hope this helps someone. Went from web development to system development over this issue. Some may call that progress! -- 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
