Description of problem:
I am having a problem with my on board sound card. Wavs play fine and so do WMA's when played in Mplayer, but if i play an MP3 or WMA in another program, it sounds crackly, and raspy. My kernel is 2.6.13-1.1532_FC4
And this is my lspci output:

Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.have intel d945psn board
2.listen to crackly MP3
Actual Results: MP3's sound very bad. Raspy, and crackly.
Expected Results: it should sound clear like the wma's and wav's.
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.
It turned out to be the Alsa driver. I changed it to OSS and the buzzing
stopped. Now I have to figure out how to do that with apps that use GStreamer.
Switching to OSS isnt a good long term solution. OSS interface is deprecated in
the kernel in favor of ALSA and OSS support might be dropped in the near future.
It would good if you can check the status with the latest kernel update and
provide feedback while working with ALSA
Thanks. I will take care of it. Thank you.
It's still not working, even after I updated the kernel with yum. Any help is
Is there any other information I can give you to help get this solved? Changing
the OSS settings in XMMS works, but not for anything Gstreamer.
reporting this to the upstream developers at http://alsa-project.org may get it
In order to fix this I had to go into all of my players and map the sound device
for PCM as hw:0,0. I hope this helps someone!
This is a mass-update to all currently open kernel bugs.
A new kernel update has been released (Version: 2.6.15-1.1830_FC4)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO_REPORTER state.
Due to the large volume of inactive bugs in bugzilla, if this bug is

Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
It's an ALSA thing, which I think they've fixed upstream. Has to do
with conversion of sounds from 44.1k to 48k or vice versa, and the
applications and/or driver requesting something which the chipset
can't do. They have workarounds at their site too.
Closing per previous comment.
