Quoting from it: > I have reported this issue to the Arch but they redirected me to here. > https://bugs.archlinux.org/task/79245 > > > Description: > When I use microphone for online meetings, my sound reaches them with a high noise that prevent it from being understood. I tested the microphone on my own and yes the noise is there. I tried pulseaudio and pipewire, but neither has solved the problem. This problem is not stemming from hardware since I do not have this issue with Windows 10. > > Additional info: > * pulseaudio: 16.1-6, piprewire: 1:0.3.75-2, kernel: 6.4.6-arch1-1 > > Steps to reproduce: > 1 - Open a chat app/website or online meeting tool like, Whatsapp, Signal, Zoom, etc. > 2 - Speak to the microphone. You can use Whatsapp and Signal to listen your microphone sound. See Bugzilla for the full thread. The reporter chose the incorrect component when this bug was being filed on Bugzilla (only generic `Kernel`), hence missing sound maintainers and I had to forward it to the mailing list instead.
