Description of problem: While attempting to reproduce a Pulseaudio daemon crash I noticed that Rawhide Pulseaudio can be crashed rather easily, by spawning an amount of client that play sound concurrently. Version-Release number of selected component (if applicable): pulseaudio-0.9.16-13.test7.fc12.i686 kernel-2.6.31-0.190.rc8.fc12.i686 alsa-lib-1.0.21-1.fc12.i686 glibc-2.10.90-19.i686 How reproducible: Always been able to reproduce the crash with 100 clients on an IBM T41 laptop. Steps to Reproduce: for i in $(seq 1 50); do aplay /usr/share/sounds/alsa/Noise.wav & done Actual results: [lkundrak@localhost ~]$ pulseaudio N: alsa-sink.c: Device hw:1 is modem, refusing further initialization.

Hm, indeed. No I wished vg would work on rawhide.
Fixed in 0.9.18 which should be in rawhide by now.
