@anthonywong Referenced report seems as unrelated. On my machine, the sound is clear and loud but 10 seconds after playback ends the noise starts.
I am not familiar with specific design of the soundcard but It looks/sounds like when it suspended by the driver, analog amplifier left active picking all kind of interferences from ground line. Kernel versions 4.4.0-1x and 4.6.0RCx are affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1468582 Title: Noisy (pop noise + white noise) headphone audio on Dell XPS 13 (2015) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1468582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
