I have launched another jack daemon controlling an alsa interface (hw:Intel)
with its internal alsa driver.

I have launched those pipelines:

* gst-launch-1.0 -v audiotestsrc freq=1000 ! capsfilter caps="audio/x-raw,
format=F32LE, rate=48000, channels=1" ! jackaudiosink client-name=testsine
name=sine connect=none

* gst-launch-1.0 -v jackaudiosrc client-name=queue0 name=in connect=none !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
jackaudiosink client-name=queue0 name=out connect=none sync=false

* gst-launch-1.0 -v jackaudiosrc client-name=queue1 name=in connect=none !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
jackaudiosink client-name=queue1 name=out connect=none sync=true

* gst-launch-1.0 -v jackaudiosrc client-name=queue2 name=in connect=none !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
jackaudiosink client-name=queue2 name=out connect=none sync=true
drift-tolerance=25000000

I reuse the previously launched "audiotestsrc ! alsasink device=DSX" pipeline
to have an external audio source.

The patchbay looks like:

This patchbay is running alongside the other.
