Here are the instructions:

1. Place a pulseaudio-9999 ebuild into your local overlay:

mkdir -p /usr/local/portage/media-sound/pulseaudio
cd /usr/local/portage/media-sound/pulseaudio
wget 
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-sound/pulseaudio/pulseaudio-9999.ebuild
repoman manifest

2. Enable your local overlay by adding this line to the end of 
/etc/portage/make.conf:

PORTDIR_OVERLAY="$PORTDIR_OVERLAY /usr/local/portage"

3. Build pulseaudio-9999 with debug symbols.

FEATURES=splitdebug CFLAGS="-O2 -pipe -g3 -ggdb" ACCEPT_KEYWORDS="**" 
emerge -av =media-sound/pulseaudio-9999

Just in case, rebuild some libraries with debug symbols, too:

FEATURES=splitdebug CFLAGS="-O2 -pipe -g3 -ggdb" emerge -1 alsa-lib speex

4. Build perf:

emerge perf

5. Restart pulseaudio as a user:

pulseaudio -k ; pulseaudio --start

6. Profile PulseAudio:

# as root:
perf record -p `pidof pulseaudio`

# while it is recording, play FEZ as a user
./FEZ
... and while the game is playing something, place a test audio-only 
call with skype. Wait for it to hang up.

# Then stop perf-recording with Ctrl+C

7. Make a readable profile report:

perf report > report.txt

My report (from FEZ + skype test call + pavucontrol) is attached. I had 
to truncate it so that it fits the mailing list size limit (100 KB). 
PulseAudio is from today's git. Please don't be alarmed by the top line 
that says 13.99%: this is 13.99% of all non-idle CPU cycles.

Here is the top of the "top" output:
