^^^ Confirmed on an XPS 13 9350 too. And the 'Headphone Mic Boost' workaround works. Although like others, I find that concerning since it should in theory make the problem worse or make no difference.
Also confirmed the problem persists with: * 3-contact earphones (Sony) * 4-contact Apple Earpods * 4-contact Bose AE2 headphones (Apple-compatible cable) All of these experience the hiss, but the Bose almost none (much harder to notice). I think the most interesting test should be to try some proper Android/Samsung/Nokia wired headphones/earphones in future. If it turns out there's nothing wrong with the physical connection then this sounds like a kernel problem still. kaihengfeng: I have just tested your kernel on zesty and it made no difference. The problem remains and the same old amixer workaround is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1654448/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
