Precisely!
I haven't checked it first-hand, but I do have a hunch that people who
experience problems with sound are mainly the people who did an upgrade from
F10, while previously fiddled with F10 configuration in order to get the sound
working.
All of my six (so far) systems using FC11 were clean installs, four from LiveCD,
one from DVD, one from DVD image NFS mounted. Oh, and a test install from USB
made from the snapshot DVD, on one of those machines later reinstalled.
Four of six had simple output to the laptop speakers work after install, the two
desktops had two channel from the sound card, no setting I've found will
enable the other speakers from any source, even on hardware which had 5.1 with
Windows and FC6.
While people on the list may or may not know what settings you have fiddled
around while troubleshooting, anaconda *definitely* cannot handle such
strangely configured systems while upgrading. AFAIK, it assumes a more-or-less
default F10 installation, where under-the-hood things haven't been customized
beyond some sane level.
So the first thing I would ask when troubleshooting F11 audio problems is "did
you do an upgrade from F10?" and if yes, "was PA working for you out-of-the-
box in F10?". This is just a hunch, but I bet 90% of people with problems
would fail to answer yes to the latter question. In that case, the only sane
thing to assume is that their system had broken configuration to begin with,
when upgrading to F11. And anaconda tries to *keep* any custom-configured
things in the system (which is the whole point of upgrading), and thus create
even more problems.
Your point about upgrade is well taken, three of the six worked worse after
upgrade from the install media to "current" using either yum (cli) or the update
menu item. Go figure.
There is a simple test to these kind of situations --- boot off a F11 Live CD,
check all mixer levels, and see if sound works out-of-the-box. If it does,
you've been bitten by your own previous configuration settings, and I would
advise a reformat and clean install of F11. If it doesn't, *then* try to
troubleshoot and whine on the list, while remembering that it is not
pulseaudio that is always the culprit. I have seen more bugs boiling down to
problems with alsa or userspace apps than problems with pa. The presence of pa
on the system mainly just reveals bugs of other components.
HTH.
Best, :-)
