Sound not working after installation

I am having issues getting my sound to work in Fedora 11.
I have been having issues since F8 when pulseaudio was introduced.
I have filed the following bug:

I am not a sound expert and have not done much troubleshooting on sound
issues so this is a little new for me.
I do know in F8 if I 'yum remove pulseaudio' my sound would work.
I don't want to do this in F11 since that is not going forward with newer
technology and is only working around the problem.

What I would like is for someone to help me in the bugzilla on getting this
fixed so that it works "out of the box" and tweaking is not necessary.
Here is the information from the bz:

Description of problem:

Alienware m15x:

Sound is not working after the installation of Fedora 11 Beta.
Sound works correctly after the installation of the latest Ubuntu

Version-Release number of selected component (if applicable):

[wade at laptop /]$ rpm -q pulseaudio

How reproducible:

Steps to Reproduce:
1. Install Fedora 11 Beta or below. (Fedora 8 works)
2. Play OGG file(s) or Flash based web video.

Actual results:
Sound is not working.

Expected results:
Sound to "work out of the box" and not needing any tweaking.

Additional info:

I apologize for any information I don't include in the initial opening of this
bugzilla.  This is my first time tracking down a sound issue.



[wade at laptop /]$ cat /proc/asound/cards

                      HDA Intel at 0xf0600000 irq 22

[wade at laptop /]$ lsmod | grep -c snd

[wade at laptop /]$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 03)

[wade at laptop /]$ alsamixer -c 0
This shows all underlying devices not muted and turned up.

[wade at laptop /]$ pavucontrol
This shows all devices listed not muted.  I have tried different sound


Looks like I'm able to get sound if I do the following:

In the /etc/modprobe.d/sound file, I added:

options snd_hda_intel model=mbp3

Rebooted and sound worked.  However, the argument is that sound _should_ be
working out of the box / after installation.

Also the output of is attached to the bz as well.
Can anyone let me know why it doesn't work after installation or what to
look for while troubleshooting sound?

Thanks in advance!
