/usr/share/alsa/alsa.conf.d/51-pulseaudio-probe.conf uses an absolute path to load 64-bit libraries installed by alsa-plugins. This precludes loading the 32-bit version of libraries installed by app-emulation/emul-linux-x86-soundlibs. Workaround: 1) Remove "/usr/lib/alsa-lib/" from /usr/share/alsa/alsa.conf.d/51-pulseaudio-probe.conf. 2) echo "/usr/lib32/alsa-lib" > /etc/ld.so.conf.d/alsa32.conf 3) echo "/usr/lib/alsa-lib" > /etc/ld.so.conf.d/alsa64.conf 4) ldconfig Reproducible: Always Steps to Reproduce: 1. emerge emul-linux-x86-soundlibs pulseaudio alsa-plugins 2. run a binary that tries to load 32-bit version of sound libraries e.g. run wine in 32-bit prefix that tries to load libasound_module_conf_pulse.so Actual Results: Library linking error. For example, from 32-bit wine prefix: ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library /usr/lib/alsa-libs/libasound_module_conf_pulse.so ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ default Expected Results: working sound system for 32-bit apps where 32-bit emul-linux-x86-soundlibs are dynamically loaded $ eix -I alsa-plugins [I]

I have observed the same broken behaviour, though I have since moved away from pulseaudio. Here's a forum thread about the (or a very related) issue: http://forums.gentoo.org/viewtopic-p-7059586.html#7059586
