I checked the new patches between rc3 and rc4, there are only some minor changes. In theory they will not introduce this problem.
Please test this dkms on the rc4, this dkms contains the same driver as rc3, let us test kernel-rc4+hda sound driver-rc3 and see if the noise still happens or not. sudo dpkg -i oem-audio-hda-daily-dkms_rc3_all.deb reboot check if there is still noise thx. ** Attachment added: "oem-audio-hda-daily-dkms_rc3_all.deb" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821663/+attachment/5251105/+files/oem-audio-hda-daily-dkms_rc3_all.deb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1821663 Title: [snd_hda_codec_realtek] repeating crackling noise after 19.04 upgrade Status in linux package in Ubuntu: Incomplete Bug description: I'm experiencing a repeating crackling noise after 19.04 upgrade that start just after the boot and before the login. I tried a bunch of fixes for pulseaudio I found googling, including this one https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling and this one https://askubuntu.com/questions/864608/audio-crackle-through-headphones. Neither of which helped. The command "killall pulseaudio" usually stop the noise for 10 seconds, then the noise restart.
