Yes, the daemon is still in the foreground.

Here are the relevant debugging bits from the output:
...
D: cli-command.c: Checking for existance of
'/usr/lib/pulse-0.9.17/modules/module-udev-detect.so': success
D: module-udev-detect.c: /dev/snd/controlC0 is accessible: yes
D: module-udev-detect.c: /devices/pci0000:00/0000:00:1b.0/sound/card0
is busy: yes
I: module-udev-detect.c: Found 1 cards.
I: module.c: Loaded "module-udev-detect" (index: #5; argument: "").
...

Apparently some other process is hogging /dev/snd/* or /dev/dsp*. Please use:

sudo fuser -v /dev/dsp* /dev/snd/*

immediately in a Terminal when you are able to reproduce this symptom,
and attach the output to this bug report.
