I've managed to fix this problem on my machine (HP Omen 15 running Ubuntu 17.04 using codec for Realtek ALC295 sound device). To fix the problem, I can do the following:
Install alsa-tools if not installed: sudo apt install alsa-tools Create and save a script in /usr/local/bin: #!/bin/bash hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67 hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000 Run the script as root in a terminal to immediately fix the problem. To run the script on startup, use cron with the @reboot command: sudo crontab -e and then add line in crontab: @reboot [full path to script] To run script on resume from suspend, copy the script to /lib/systemd /system-sleep For more technical details regarding this fix, see https://bugzilla.kernel.org/show_bug.cgi?id=195457 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1648183 Title: Crackling and popping sound when using headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
