Red Hat Bugzilla – Bug 443537
kernel: ALSA sound/core/pcm_lib.c:154: BUG:
Last modified: 2013-01-13 09:02:18 EST
Description of problem:
PulseAudio Volume Control causes kernel bug when I open it during a youtube
playback under Firefox3.0-0.54.beta5.fc9 as on Fedora 9 Live prerelease.
Version-Release number of selected component (if applicable):
1. Install Fedora 9 i686 Live on a USB key and boot.
2. Bring up Firefox
3. Surf to youtube.
4. Search Vivaldi Mandolin, choose Vivaldi Mandolin Concerto - Evan Marshall and
5. Note that flash needs installing, follow the steps and it will install, open
another Firefox window and do "about:plugins" to get Firefox to know, in the
youtube window do Control-R to retry.
6. Note there is no sound, at least not on my HP ze5250 laptop
7. Do Alt-F1 -> Sound & Video -> PulseAudio Volume Control
8. Note in /var/log/messages that the text in the above abstract has appeared.
Steps to Reproduce:
1. Oops, see above. Reproducible every time.
Sound plays in the youtube video (by the way, picture is fine already) and no
kernel error message occurs when PulseAudio Volume Control is brought up.
We need to see the complete message. Can you run the 'dmesg' command after the
error occurs and upload the result?
The dmesg command shows six occurrences of the following, on six consecutive lines:
ALSA sound/core/pcm_lib.c:154: BUG: stream = 0, pos = 0x1138, buffer size =
0x1138, period size = 0x44e
No more detail is shown by the dmesg command than this. Hope it helps.
What kind of sound hardware is it? Can you post the output of 'lspci -vnn'?

Sorry I didn't know to change status to ASSIGNED after I provided the requested
information. (I'd thought it would happen automatically, I guess.) Is this right?
Changing version to '9' as part of upcoming Fedora 9 GA.

lspci output and messages log
Oooops, forgot the comment:
I'm getting similar problems with any audio (I mainly use Exaile) and a
Soundblaster card. The position changes with each line, and using OSS instead of
ALSA/Pulse Audio means I can have sound, but I'd rather use Pulse Audio.
Attached is the "lspci -vnn" for my machine and the contents of the
/var/log/messages from boot to the point I took it (not long after logging in).
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
