[pulseaudio-discuss] Allowing pasuspender from other users
I recently set up a couple of extra accounts on my desktop machine for my roommates to use. The only time they'll ever be using it is when I'm already logged in on another console, so pulse will always be running as me. When they log in, things like paplay work just fine, and they're able to use the pulse output module in audacious to listen to music. However, I've been trying to get them set up to play games using snes9x which, AFAIK, uses OSS for sound output. Whatever it is that it does, even padsp can't support it, so the only way I can run it is using pasuspender. Using pasuspender it works great. Now the problem is, other users can't use pasuspender since pulse is running as me. I've tried creating a SUID script (launched by an SUID elf file, since interpreted suid bits don't work), but it doesn't work. (This is a bad idea anyway, but it's the first solution I could come up with.) So is there any way to allow other users to run pasuspender and have it work? I don't mind if I need to greatly lower the security settings for pulse. Things like auth_anonymous=1 are fine if they'll get the job done. -- Alex Malinovich Support Free Software, delete your Windows partition TODAY! Encrypted mail preferred.

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

The problem is: I want to listen to a 'source' on the Win PA server! The data is available as something like a virtual line input. Normally one would use rtp-send to forward this stream as described in the documentation but the rtp modules are not available on windows. And since I'm not very familiar with windows I have to be happy with what I have on the windows side. I'm able to tunnel my Win PA source stream to the Lin PA. As expected I'm getting a new source inside my Lin PA. And when I start a vumeter for this source stream I can see the music I would like to hear. What to do then, how to send the stream data from a source to a sink? Maybe something like: PA source -> socket -> netcat -> socket -> PA sink via the simple protocol or PA source -> gstreamer -> PA sink or any other idea? regards, ulf ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

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
Re: [pulseaudio-discuss] remote source to local sink
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 cheers ulf ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

Not exactly sure what you're trying to accomplish here? 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.

If you were wanting to play something in itunes and have it coming out your windows speakers etc., then walk over to your linux box and somehow access this stream also (e.g. keep it playing out of the windows speakers), then this too is possible (this scenario is what is described by the title "remote source to local sink" - what I described above was a "local source/stream to a remote sink" i.e. I was considering the windows PC to be local). It may be that what I described is what you mean but hey You can on the linux box hook into the "monitor source" of the windows pulseaudio daemon. You can, in theory, just play this remote stream using e.g. pacat but in the short time I have to test I couldn't make it do this... no doubt some brain dead thing I'm doing ;) However, to illustate the point, you can use gstreamer. Here in this example below is a gstreamer pipeline that will display music-matched visualisations on linux from the sound playing on a remote machine. In this example my remote machine is called "plateau". The stream playing on that currently is actually the result of a tunnel from a colleagues machine but that doesn't matter! PULSE_SERVER=plateau gst-launch-0.10 pulsesrc device=alsa_output.pci_10de_6a_alsa_playback_0.monitor ! audioconvert ! libvisual_bumpscope ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv, width=640, height=480 ! ffmpegcolorspace ! ximagesink To explain: # Name of the server PULSE_SERVER=plateau # The gstreamer pulsesrc to grab the audio.

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/ 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?

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.
