I don't know if this is entirely relevant but I had stuttering audio
when
playing music in Amarok in a newly installed F10 system. After
searching
for solutions for ages I eventually found a link which suggested"
he PulseAudio sound server has been rewritten to use timer-based audio
scheduli
ng instead of the traditional interrupt-driven approach. Timer-based
scheduling
may expose issues in some Alsa drivers. To turn timer-based scheduling
off,
repl
ace the line
load-module module-hal-detect
in /etc/pulse/default.pa by
load-module module-hal-detect tsched=0
"
After doing this and rebooting then sound in pulseaudio was fine on
that
system.
So sometimes there is documentation, and if we are lucky then it fixes
our
own problem, but clearly newly developed and released software can and
does
still have issues. If we report on the BZ appropriately and give
suitable
diagnostics hopefully the code will get fixed - and yes I saw the
ding-dong
quoted earlier in this thread.
Sound is not the only issue - there are fixes needed for plymouth,
xorg.conf-free X, SElinux etc etc etc....
The cost of making progress......

For what is is worth...
My puulseaudio was awful. It used 70% of my CPU tyring to watch a film
in mplayer, etc. This post made me look at the config, and I say there
was a daemon.conf from September and a daemon.conf.rpmnew.
The old one had things like:
nice-level -11
realtime-priority = 5
When I swapped to the rmpnew conf file things got much smoother.
