During the upgrade of my server to Ubuntu 8.04 LTS pulseaudio was installed as the central sound server. By using pulseaudio it is possible to receive, mix and play multiple audio streams simultaneously, even from different machines, to an e.g connected to 5.1 surround system. That way I am able to receive radio streams on the server and at the same time getting sound from games played on a different machine using the same audio equipment.

I enjoy playing Everquest 2 using wine on my gentoo amd64 box. Works like a charm currently using wine version 1.1.3 btw !
Playing games on linux leads to wine most of the time. Wine is a 32bit application ( guess why ) , my gaming box runs gentoo amd64. Wine uses either alsa or OSS to get sound working. Despite the favor for alsa by the wine developers, OSS seems to work better at least for Everquest 2. In order to route OSS audio to a pulseaudio server, you have to use padsp to wrap audio playback. See recommended Pulseaudio OSS setup.

That's where the trouble started.
padsp needs libpulsedsp.so 32bit, which is currently (ebuild 20071125) not part of the emul-linux-x86-soundlibs ebuild. I setup a chroot32 following the quite good chroot32 guid on AMD64 in order to compile the needed libraries myself. If you don't want to compile them yourself you can get them here until they are added to the upstream ebuild (bug already filed). Extract the archive under /usr/lib32.

Additionally you need various alsa plugin 32bit libraries to get rid of all errors and warnings. All libraries for the alsa plugins from the alsa-plugins ebuild are also missing in the emul package, so if you want get them here. This archive needs to extracted under /usr/lib32/alsa-plugins.

Update: I added libsamplerate.so and libpulse-simple.so. Amongst others, this should make libflashsupport work, thx Per for the point.

Update: By using the latest emulation libraries (app-emulation/emul-linux-x86-soundlibs-20091231) from upstream pulseaudio works !!
