Comment 21 for bug 273693

correction on the last comment: dmitry's latest fix works, as long as you also execute steps 3 and 4 of the previous fix (sudo ldconfig + edit /usr/share/alsa/pulse.conf)

also note that my error messages where:
ALSA lib ../../src/conf.c:2700:(snd_config_hooks_call) Cannot open shared library /usr/lib/alsa-lib/libasound_module_conf_pulse.so
ALSA lib ../../../src/control/control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
