+I also have an external sound card, a Scarlet 2i2 G3, that I would like to use as my default audio output. However, it might not be always connected, hence the following code:
+#+NAME: default-soundcard
+#+BEGIN_SRC fish :tangle no
+  set SOUNDCARD "alsa_output.usb-Focusrite_Scarlett_2i2_USB_Y8KJ6NH094EF1C-00.analog-stereo"
+  pactl list short sinks | grep $SOUNDCARD 2&> /dev/null && pactl set-default-sink $SOUNDCARD
+#+END_SRC
+
 #+BEGIN_SRC fish :noweb yes
   set -l PATH $PATH /usr/lib/xfce-polkit
 
   <<autostart-gen()>>

 #+END_SRC
