Everything worked fine on F9 for me without pulse.  I tend 
to keep flash turned off, though, only enabling it as 
necessary, so I might have missed problems.

I don't run pulseaudio because I don't need it, so I can't 
help you there.  http://www.pulseaudio.org/

Read the document at one of these links.  While it is about 
hd-audio, some of it applies to standard sound issues.  Pay 
particular attention to the suggestion for the alsa-info.sh 
script.

You can get the text from web:

If you are not going to use pulse, you can create an audio 
group (as root) and add your user to that group.  This gives 
alsa access to (somewhat) real time processing.  I say 
somewhat because this is the kernel built in real time, not 
Ingo Mjollnar's real time patch.  (Name may be wrong).

groupadd audio

usermod -a -g audio <your userid>

If you are going to use pulse you need to add yourself to 
the rtprio group (I think it is that).  Test by doing a
pulseaudio --kill to see what it says.  It should tell you 
the name of the group in the error message.
