[pulseaudio-discuss] How manage volume remotely on pulseaudio

[Christian Schmitz]

Dear Matt
	I have full access to the machine, ( i install it for my wife and kid). Sadly 
i dont know how do ssh with X forwarding. So i go for pactl.

user at kid > pactl 
no valid comand
user at kid > pactl 
Big big list of things.

i get some of sucess doing:
pactl set-sink-volume 0 32768

There are some tool more friendly that pactl, with look similar to alsamixer 
or etc?

Best Regards
Christian
