[SOLVED] Mic producing echo in Discord web client

I'm using Pipewire and Wireplumber. My setup is a pair of stereo and a separate mic. There are 2 monitors and they maybe have speaker on them.
Everytime I speak my voice would echo and the amount of echo increase as my volume output increase. I tested with OBS recording but there was no echo albeit there are a bit of static (sound sounds like they're broken somehow). When I listen to music sometimes the audio will stop for a fraction of second but that is maybe another issue.
I also tried installing noise-suppression-for-voice package but it only work until the output volume is at 55%. Any help will be appreciated

Re: [SOLVED] Mic producing echo in Discord web client

Web Discord doesn't have the noise and echo cancellation features of the desktop client.

Web Discord doesn't have the noise and echo cancellation features of the desktop client.

You were right. The client version didn't have echo issue. But I guess it's kinda weird it's happening on Linux and not Windows. (I'm brand new to Arch so idk)

Perhaps your Windows audio driver is better at noise cancelling and echo cancelling.

Always use the client. I lowkey wished there was an option to disallow web users from voice chats per default.
