I have two computers. Computer A is running Ubuntu 11.10 with Gnome Clasic. Computer B is running Mythbuntu 11.10. Computer B has a sweet digital audio sound system.

I want to play music from Banshee on Computer A, but have the sound output sent over the LAN and come out on computer B's speakers.

I found this question which indicated I should use something called "paprefs" to acheive this. So, I installed paprefs and then in the "Network Server" dialog, I selected these settings:

paprefs

And then... I have no idea what is supposed to happen. I checked the paprefs home page, and all they say under Documentation is "There is not much to say. Just run paprefs and see for yourself."

I don't see anything happening or any way I'm supposed to make the connection from Computer A to Computer B.

How is this supposed to work? Can someone provide clear instructions on what one does to actually make the connection?

Ideally, the hope is that I can have a set up that allows me to always play certain applications, like Banshee, over the LAN using Computer B's sound system. In other words, once set up, it is the default, and does not have to be manually reconnected every time.

The least complicated method to send audio from one Pulse Audio server to another over the LAN is to use the RTP/Multicast feature that you are able to set up using paprefs Install paprefs

On the sender:

Choose your local soundcard or choose a separate device you can select as audio output from Audio Preferences.

On the receiver:

By doing so audio will be sent from the sender to the receiver via your LAN.

Thank you for this. I did this settings as you described, yet if I play Banshee on the Sender, I'm not hearing it on the Receiver. I also don't see any network sound device in pavucontrol or any gnome sound settings. Are there no other steps I need to take? –  Questioner Oct 22 '11 at 16:07
    
Got it sorted. I had to: 1. Reboot both machines. 2. On the Sender machine, go into sound settings, and under the "Output" tab, select the network sound device. –  Questioner Oct 22 '11 at 17:11
    
Just did this. Got massive lag and it made the server PC really sluggish... possibly something I'm doing wrong, but as it only involves ticking two checkboxes, I don't really know what could go wrong. –  Greg Apr 24 '13 at 12:06
    
@Greg: depending on your network, and on the audio content (bitrate!) this streaming method can be quite demanding. In case you have issues try to reset pulseaudio with pulseaudio -k this occasionally helps. –  Takkat Apr 24 '13 at 20:16

See this guide for another simple method which allows you to select from the servers' sound cards on the client.
