Audiomixer clicks with live source

[paul.goulpie]

Hello,
 
When I try to use the Audiomixer plugin with several live sources, I hear
clicks on the audio output.
Example with the following command line:
gst-launch-1.0 \
audiotestsrc freq=440 is-live=true ! volume ! audiomixer0. \
audiotestsrc freq=450 is-live=true ! volume ! audiomixer0. \
audiotestsrc freq=460 is-live=true ! volume ! audiomixer0. \
audiotestsrc freq=470 is-live=true ! volume ! audiomixer0. \
audiotestsrc freq=480 is-live=true ! volume ! audiomixer0. \
audiomixer ! volume ! tee \
tee0. ! queue ! alsasink
 
Clicks are noticeable.
 
With the following command line:
gst-launch-1.0 \
audiotestsrc freq=440 ! volume ! audiomixer0. \
audiotestsrc freq=450 ! volume ! audiomixer0. \
audiotestsrc freq=460 ! volume ! audiomixer0. \
audiotestsrc freq=470 ! volume ! audiomixer0. \
audiotestsrc freq=480 ! volume ! audiomixer0. \
audiomixer ! volume ! tee \
tee0. ! queue ! alsasink
 
No perceptible clicks.
 
Would you have an idea, allowing me to use the plugin audiomixer with
several live source without signal deterioration.
Thank you in advance.
