This depends on the hardware design first, if the audio jack and the codec supports it or not.
Then it depends on the kernel driver. With the ubuntu 20.04, the userspace part is OK to support the headset button, since I already verified it on the Leonvo x1c7. I will build a testing kernel, let us see if it could work or not. thx. ** Changed in: pulseaudio (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894338 Title: [Samsung Earphones Tuned by AKG] Volume control buttons don't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
