View Full Version : [ubuntu] PulseAudio Speakerphone Feedback Loop: How can I prevent this

May 1st, 2010, 07:27 AM
I'm trying to use SFLphone, a VOIP client, as a speakerphone (meaning audio through speakers that the microphone can hear). This always results in a horrible feedback loop because the microphone records the speaker output, which is played through the speakers, which is recorded....and so on. This application uses pulseaudio, so my question is: can PulseAudio be used to prevent this horrible effect?

I'm sure it can, I'm just hoping that someone has a ready-made solution.

edit: The SFL people were working on this before I posted, how nice! https://projects.savoirfairelinux.com/issues/show/1966

It's an excellent softphone, btw.

Still, it'd be cool to know how to implement this in pulseaudio!
