I want the default PulseAudio sink to change to HDMI when HDMI is plugged in, and back to analog when disconnected. I want the default PulseAudio sink to change to HDMI when HDMI is plugged in, and back to analog when disconnected.
Changing the default sink in pulse is as easy as running `pacmd set-default-sink <sink id>` where `<sink id>` is the id of the desired sink. Unfortunately, this is another situation where the id might change unexpectedly. We also don't have an easy interface to determine the id number from a name like we did with `xinput(1)`, so we're forced to parse the output of `pacmd list short` like so: Changing the default sink in pulse is as easy as running `pacmd set-default-sink <sink id>` where `<sink id>` is the id of the desired sink.

This command lists all sinks in short form, then greps for a line containing "hdmi", uses grep to only print the first character (the sink id), then sets the default sink with `pacmd(1)`. Since this will also need to be run any time the display configuration changes, a function is, again, appropriate: This command lists all sinks in short form, then greps for a line containing "hdmi", uses grep to only print the first character (the sink id), then sets the default sink with `pacmd(1)`.

This allows you to change the default PulseAudio sink with `setpasink <name>` where `<name>` is any arbitrary string that is unique to the line that corresponds to the desired sink in the output of `pacmd list short`.
