pulseaudio and multiple applications

[KhaaL]

I had high expectations for pulseaudio to magically let me play several non-alsa applications toghether. However as it is right now, I can't even play several alsa applications at once... Yes, I'm back to the oss era. Let me give you an example:

Before I was able to play music on amarok and enjoy quake wars or any other game on wine. Now I can't do that, even though all three worked fine with each other when I ran ALSA in gutsy gibbon.

Have I forgot to configure something in order to make it run as it's intended to be?

here we go again!

i seriously hope you're the exception rather than the rule

Way to enlighten me on the subject :rolleyes:

FYI i did search for threads regarding pulseaudio and didn't find much help.

Here comes the light ;-) :

Install the following packages (if you haven't already installed them) :

gstreamer0.10-pulseaudio (Gstreamer-pulseaudio-plugin)

libao-pulse (pulseaudio for libao. Some application are based on it)

libsdl1.2debian-pulseaudio (Pulseaudio-driver for libsdl. Replaces the package "libsdl1.2debian-alsa")

libasound2-plugins (Pulseaudio-plugin for ALSA)

After installing these packages you must activate pulseaudio for ALSA, Gstreamer and libao :

1. Gstreamer is very easy. Start "gstreamer-properties" or "System->Audio" and select "Pulseaudio" for each entry.

2. For ALSA you must open a console an type in "asound set-pulseaudio". Thats it. ALSA now uses Pulseaudio as default "soundcard"l

3. For libao you must edit the file "/etc/libao.conf" and change the entry "default_driver" from "alsa" to "pulseaudio"

4. SDL uses Pulseaudio automatically. There is no change needed.

That's it. All applications should now use Pulseaudio.

awesome little guide! :D I had to make one small change:

the command asound dosen't exist, the command is therefore asoundconf set-pulseaudio

I'm a little suprised that the neccesarly changes in 8.04 haven't been made considering its using pulseaudio by default. I'm gonna play around and report back how well things work.

Edit: I also have issues with flash 9 (v 9,0,115,0) sound, even with libflashsupport installed.
Edit2: I tried changing FIREFOX_DSP="none" to "aoss" and to "esd" in /etc/firefox-3.0/firefoxrc with no luck

Alright, for gstramer it worked nicely! but for ALSA there is no improvement, nor in OSS. I haven't tested any games / applications dependant on SDL or libao yet

I've had the same problem since pulseaudio was first included. Unfortunately, pulseaudio works with everything but wine. I'm stuck with alsa for now.

[KhaaL]

I've been wrestling with this for 6 hours and I'm not really getting anywhere. Since the main apps I run dosen't go well with PA (flash 9, ETQW, wine), I'd rather remove it and revert to ALSA.

Is that done in Hardy Heron by simply... " Remove the added lines to /etc/asound.conf. After this, you may remove all of the installed PulseAudio packages. "? (taken from pulseaudio ubuntu wiki).

padsp winecfg choose OSS, then start every wine app with padsp wine app.exe Should work fine.

I forgot to add the package "libflashsupport" to my list. This package adds pulseaudio-support to Flashplayer v9.

For ALSA-only applications the command "asoundconf set-pulseaudio" will do the magic (See my first post).

I've tried this, but still doesn't work with warcraft 3.

EDIT: Finally figured it out. For anyone who is using 64bit you need the 32bit libraries.
This will fix flash/wine.

You will need these 32bit packages:
libasound2-plugins
libcap1
libflashsupport
libpulse0
pulseaudio-utils

Get them here:
http://archive.ubuntu.com/ubuntu/pool/main/libc/libcap/
http://archive.ubuntu.com/ubuntu/pool/main/p/pulseaudio/
http://archive.ubuntu.com/ubuntu/pool/universe/libf/libflashsupport/
http://archive.ubuntu.com/ubuntu/pool/main/a/alsa-plugins/
Open data.tar.gz for each package and go to /usr/lib/.
Extract everything to /usr/lib32.

Here's a screenshot of it all working in pavucontrol.

I've both libflashsupport installed and asoundconf set-pulseaudio command made, with no improvement unfortunatly.

I actually om 64bit, so that could be the problem. however, I have all those mentioned packages installed through apt-get.

You need the 32bit libraries. I.E. those with i386 at the end. Right now you have the 64bit libraries installed.

And force them through dpkg -i --force-archotecture?

sudo dpkg -i --force-architecture libasound2-plugins_1.0.15-1ubuntu3_i386.deb libcap1_1.10-14_i386.deb libflashsupport_1.9-0ubuntu1_i386.deb libpulse-browse0-dbg_0.9.9-1ubuntu2_i386.deb

That's probably a bad idea. You only need the libraries. Open each .deb in file-roller, and then open the data.tar.gz.

Navigate to /usr/lib.

Extract whatever is there to /usr/lib32.

That helped with both flash and alsa games. However everything is now playing with a 2-3 second lag, wether i have another sound application running or not

where have u got that sound panel?? mine still looks like the normal one :S:S

--edit--

duhh sudo apt-get install pavucontrol
