Title: Headphones have a faint square/triangle wave sound when unmuted Status in pulseaudio package in Ubuntu: New Bug description: This issue can be replicated on both Ubuntu 21.10 and 22.04 installs, but is not present on the live USB version of either. It is also not an issue on Fedora 35 (using aplay directly to device) nor Windows 10. The issue can be resolved until reboot by unplugging and replugging several times, as well as switching between speaker and headphones. I am not sure of a deterministic way to replicate this workaround. Alsamixer reports the chipset as ALC287, but according to specs it is actually an ALC3306. I am not sure if this is related. I can do any additional testing as necessary to narrow down the issue.
