I want a very simple setup where i can podcast via studio-link with my headset.

Therefore i have:
* Headset Mic ( alsa_output.CODEC.analog-stereo.monitor )
* Headset Speaker ( alsa_input.CODEC.analog-stereo.monitor )
* studio-link recording
* studio-link playback

I need to create an extra streaming audio device and loop what i hear and what
i speak into this device:


.. code-block:: bash

  ~ pactl load-module module-null-sink sink_name=stream sink_properties=device.description="Streaming_Output"
  22
  ~ pactl load-module  module-loopback source=alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo.monitor sink=stream latency_msec=1
  23
  ~ pactl load-module  module-loopback source=alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo sink=stream latency_msec=1
  24

Now lets open studio-link, set playback to **CODEC Analog Stereo** and
Recording to **CODEC Analog Stereo**.

we start darkice with a configuration like this:

.. code-block:: ini

  [general]
  duration = 0
  bufferSecs = 5
  reconnect = yes
  realtime = no
  rtprio = 2

  [input]
  # pactl load-module module-null-sink sink_name=stream sink_properties=device.description="Streaming_Output"
  # pactl load-module  module-loopback source=alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo sink=stream latency_msec=1
  # pactl load-module  module-loopback source=alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo.monitor sink=stream latency_msec=1
  sampleRate = 44100
  bitsPerSample = 16
  channel = 2
  device = pulseaudio
  paSourceName = stream.monitor
