Hello Raymond, i have tried what you said, and i noticed something. I tried hda-analyzer, as mentionned, checked Node[0x1a] PIN
In the Widget Control, if i uncheck the IN option, i get the noise i mentioned earlier. I attached a screenshot. ** Attachment added: "Screenshot from 2016-01-15 21-27-58.png" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1534434/+attachment/4550830/+files/Screenshot%20from%202016-01-15%2021-27-58.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1534434 Title: [20BVCTO1WW, Realtek ALC3232, Black Headphone Out, Right] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1534434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
