Hi,

I got a hint from daviko, that they will include this option in their 
next Linux release!


Cheers,
Hauke

It is possible to PulseAudio configuration hints using environment variables.
When using the command line, you can tell it to activate echo-cancellation like 
this:

 PULSE_PROP="filter.want=echo-cancel" ./PlaceCam/opt/PlaceCam/PlaceCam

Oleg and me tested this and were surprised how well it works.
I hereby encourage anyone using Linux to adopt this method so the audio in our 
virtual meetings will be less painful.

I do this, but it does not qualify as super-convenient.
Mainly because it requires me to navigate my mouse to the PlaceCam window and 
click the tiny button.

Well, you can mute yourself, whenever you're not speaking, so it would be
something like click-to-talk.

I would like to add a research topic though:
Figure out how to save/restore audio settings per application instead of per
PID - or at least set the Mic settings to a more sensible default value.

Cheers,
Oleg
