How do I turn off audio echo from microphone to local speakers?
Sound Settings (GUI)
In "Sound Settings..." choose Hardware and change from "Analog Stereo Duplex" from the Profile selection to "Analog Stereo Input" for usage as microphone or "Analog Stereo Output" for use as speakers.
Command line
From the command line we need to know the index
and possible profiles
of cards installed. Both will be listed with
pacmd list-cards
To change the card profile we may issue
pacmd set-card-profile <index> <profile>
Where we have to give appropriate values for the card-index we want to set up, and the profile desired.
Examples
The following examples show the commands for a standard internal audio card with index 0
for values corresponding to the GUI:
pacmd set-card-profile 0 input:analog-stereo # for Input
pacmd set-card-profile 0 output:analog-stereo # for Output
pacmd set-card-profile 0 output:analog-stereo+input:analog-stereo # for Duplex

From 2 microphone inputs I have only one in use. When I talk into my USB microphone the audio echoes back to my local speakers (my "hello" is getting looped back instantly).
How do I turn this off?
Additional information on how to do this from command line (for a remote machine) would be appreciated.
