Um, it's just an example? Does this somehow help?

1. (term1) `ssh remote pulsemixer`

2. (term2) `ssh remote "pacat </dev/urandom"`

Observe that (1) you can see a new client appear on the remote, and (2) audio will play from the default playback device on the remote (and you can trivially change that device with `pulsemixer`)

EDIT: for your speakers/ears-sake, I recommend turning down the default playback device before doing this.
