Old notes on pactl - when the RME Fireface UFX was
connected to host "ig1". It is now connected to another
similar host "solo" with the same setup. Apologies, but
i am not sitting at solo right now (it's in another building)
and so cannot access the user's login to run pactl. Note that
pulseaudio runs as a user process, not a system process, so
an 'ssh solo' or 'su' on that machine to that user will not
have sufficient permission (X11). 


However, this should still be informative. Can send actual
current output from pactl upon request :)

The username and RME Serial No has been redacted with '***'

* Really need to grok pactl - pulseaudio control
  eg: (pactl commands below)

  - note default channels are 2
  - note need to su to ******** as that's who is running pulseaudio!
