This might look like a duplicate of #138 or #311, but I promise it's
different: AFAIKT I am not loading module-detect and I am only loading
module-alsa-sink one time.
I am using a Lenovo SL300. The sound card and alsa work correctly (tested
with aplay and gstreamer-based applications). However, with no processes
using the sound card (according to lsof), when I try to run
pulseaudio-0.9.13, I get:

So it looks like pulseaudio can load alsa source, but for some reason
cannot load alsa sinks...
