Hi! I have echo when I speak. And I have this problem when I use REDMI Buds 8 Lite (headset) or Ryzen HD Audio Controller Analog Stereo. Monitor doesn’t work. And I have this problem in zoom, google meet, discord, viber and in different browsers like mozilla, chrome etc. I download audio-recorder and with REDMI Buds 8 Lite it works fine, with Ryzen HD Audio Controller Analog Stereo there are noises. Comment: In Windows sound works fine with internal micro or with headset.
I don’t even have a microphone and wasn’t really chiming in to help only to point out that the 2 distro’s are very different. Arch is Rolling release with the latest and greatest. Ubuntu is yesterdays software. As far as your echo issue I have no idea. Maybe someone who is more familiar with your issue will chime in.
