There is a known problem for some those 4-speaker configurations with only two DACs. In the realtek driver code, it expected to assign all 4 speakers to a single stereo DAC while a headphone is bound to another stereo DAC. However, the actual behavior is to bind the main speaker to one DAC and both the bass speaker and the headphone to another DAC. In short, the volume for both bass speaker and headphone are tied, so the volume control can go weirdly upon plugging/unplugging.
I submitted a fix for those misbehavior today to the upstream: https://lore.kernel.org/[email protected] Let me know if this gives improvements in some cases or cause another trouble. Note that, with the patch applied, the individual "Bass Speaker" volume will disappear. That's intended behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958019 Title: [Lenovo Legion7 16ACHg6 82N6, Realtek ALC287, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/sound-2.6/+bug/1958019/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
