This started affecting me with the kernel update to 4.4.0-112-generic on xenial. I booted the old kernel and the issue went away. Tried a few times back and forth and the 4.4.0-112 kernel consistently has the sound dropouts, while 4.4.0-108 does not.
Also tested with 3 different audio cards (by varying manufacturers), same result on each. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576420 Title: [H55M-D2H, Realtek ALC887, Green Line Out, Rear] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1576420/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
