Which says:
o change the default sink (output):
# pacmd set-default-sink 3
To change the default source (input):
# pacmd set-default-source 3

This can also be set in /usr/local/etc/pulse/

Replace the number '3' with the new default your want to set.

The audio/freedesktop-sound-theme is needed if the default sound files
are uncommented in the /usr/local/etc/pulse/ file.

I have tested there in the file 0 and 1, without much more sound. How
can I get and understand the correct values to put into the file?
