Daniel, over the span of this thread users have been experiencing this on 18.04, the topic contains information regarding users (Including myself) testing this on 18.04 and effects all distro's i know because of a bug in the current version of the snd_hda_intel driver.
The related open kernel issue can be found here : https://bugzilla.kernel.org/show_bug.cgi?id=195303 . While i haven't tested for its presence in Ubuntu 18.10 the bug was still present in 18.04 earlier this week as confirmed by a discord friend who found my voice distorted in the way this bug describes. Using a newer kernel on 18.04 does not fix the issue as the issue has not yet been addressed on a driver / pulseaudio level. ** Bug watch added: Linux Kernel Bug Tracker #195303 https://bugzilla.kernel.org/show_bug.cgi?id=195303 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1716654 Title: [System Product Name, Realtek ALC1220, Pink Mic, Rear] Underruns, dropouts or crackling sound Status in alsa-driver package in Ubuntu: Won't Fix Bug description: Have checked under windows (same computer in dual-boot & same headset), and the sound is crystal clear, so 99% sure this is not a hardware problem.
