Disclaimer: I've not used pulse on windows (been meaning to for a while - perhaps sometime soon! - I'm using module-tunnel-source to connect from my linux desktop to the windows PC. Why is the tunnel module deprecated? What do I loose using this module? And how do I establish this connection directly as it is recommended in the documentation? Module tunnel is not deprecated. I use it all the time (linux-linux in my office and at home!). So in your setup you have your audio source on your laptop/itunes and the actual sound card on your linux box. Both should be running pulseaudio server. ON the itunes machine you should tell pulse to load module-tunnel-sink. This creates a local virtual audio device on your local machine which actually outputs to the network attached device.. You can then switch the stream played by itunes to this virtual device using pavucontrol (assuming this works in windows?) You need to make sure that the server pulseaudio is configured to allow connections from the network (e.g. with authanonymous or and ip based ACL rule). Most of the information can be found on the pulse audio wiki, but I think there is probably call for some Scenarios to be put up there which give real step-by-step examples of how to achieve a given setup. I'll maybe try to do that sometime. FWIW, the best way to do this is to enable autodiscovery - this works great on Linux but again I'm not 100% sure how things work on windows. Essentially you need to make sure the server (or all pulseaudio daemons) have the zeroconf-publish module loaded. This uses Avahi/Bonjour/Rendevous/insert new name here to automatically broadcast the fact that the machine supports a pulse audio sink. You can then use the zeroconf-discover module on the client to automatically load module-tunnel-sink when it detects these broadcasts. These settings can be configured via paprefs. - finally I have the stream I want to listen to as a source in my pulseaudio server on my linux PC. How to forward to the sink? I've tried to use rtp-send with option loop=1 and rtp-rcv on the same pulseaudio instance.

So I'm looking for something like the 'virtual audio cable' for internal use in pulseaudio. Any hints? Anyone already working on a solution? What you want to do is possible now so no need to worry about it. I think you may be getting your sources and sinks mixed up. You're stream on your itunes machine should go something like: itunes - win-pa - tunnel --- lin-pa - soundcard - speakers - ears Hope that helps. Swing by #pulseaudio if you're stuck. /me really needs to play with windows at some point.

If you're trying to play audio on your Linux box and have it come out on the speakers for the Windows box that's pretty easy to do over the network. If, on the other hand, you want to play audio on your Windows box and have it come out of the speakers on the Linux box, that's considerably harder. You would have to have a virtual Pulse soundcard in Windows, which, AFAIK, doesn't currently exist. There is a virtual ESD soundcard for Windows, but it hasn't been updated in years and never worked quite right from what I understand. There might be some other way of accomplishing this, but I don't know it. -- Alex Malinovich Support Free Software, delete your Windows partition TODAY! Encrypted mail preferred.

Ulf Behrens wrote: sorry for being not very precise on what I want to do. Let me try again: I want to listen to some drm restricted music coming from napster or itunes The only speakers which are worth to be called speakers are connected to a linux box (in my office as well as at home). I don't need any 'noise' coming out of the speakers of my laptop, but my laptop is the only windows computer around. I was already able to get a test setup running but I'm not happy with the network traffic I'm producing: I'm sending the data once via a tcp connection from my laptop pa server to my linux pa server and then the linux server is sending the data once again via rtp to itself. In order to avoid the rtp traffic I'm looking for a way to send data from a pa source to a pa sink. As Colin proposed I'm going to look into gstreamer which seems to allow what I want Judging by your comments above, I'd go back to my previous mail before I suggested the whole gstreamer thing. What you want is a tunnel from laptop to linux. Then you just want to move the output stream to the tunnel. This is a very simple setup and doesn't require any complicated setup (at least on linux-linux - I've not tried on Windows so perhaps something doesn't work properly on this platform. I will need to play to say for sure!) The pipeline I suggested before was correct I think: iTunes - Win PA server - Tunnel from Win-Lin - Lin PA server - soundcard - speakers - ears. It's just that the subject of the mail made me thing you were wanting the control to be in the opposite direction! Personally a better subject would be How to output to remote linux pa sink from windows pa server? Of course I'd just recommend stripping out the DRM and slapping everything in Amarok myself but that's another point ;) Col ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

Well you could definately do it via gstreamer - that's fairly easy to do. I would have through pacat should be able to do it too tho', but I've not quite found the right command ;) Since I'm not too familiar with gstreamer, I don't say it definetely won't work, but I'm quite sceptical. The reason I think it probably doesn't work (or maybe works, but badly) is that the pipeline is clocked in both ends, and they don't share the clock. For the same reason the pacat solution won't work either. The audio needs to be resampled between the source and the sink. I'm not aware of any solution to this apart from RTP. If RTP isn't used for anything else, the extra network traffic could be prevented with firewalling in the Linux machine. What really is needed is a proper virtual pulse sound card for Windows. -- Tanu Kaskinen ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss
