Description Jerry James 2007-11-12 16:43:18 EST
Description of problem:
In Fedora 8, any use of sound by XEmacs leads to an assertion failure in the
sound code.  The easiest way to trigger the problem is to press Ctrl-g in a
fresh XEmacs.  The inability to use Ctrl-g seriously hampers the usability of
XEmacs.  The crash message is:

xemacs: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed.

Fatal error (6).

... followed by the usual XEmacs crash message.  The Lisp backtrace only shows
that "ding" was called.  The C backtrace is as follows:

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

How reproducible:

Steps to Reproduce:
1. Start XEmacs
2. Press Ctrl-g
Actual results:
XEmacs crashes with an assertion failure.

Expected results:
XEmacs plays a beep sound.

Additional info:
I'm the guy who wrote XEmacs' ALSA code in the first place, so this is probably
my fault somehow. :-)
Comment 1 Will Woods 2007-12-03 14:36:22 EST
This works fine for me with a freshly installed xemacs; did you have to do
something to enable ALSA magic? I just get a PC Speaker beep rather than
anything through the audio device.
Comment 2 Jerry James 2007-12-03 14:50:05 EST
Sorry, I added this to my .xemacs/init.el so long ago that I had forgotten all
about it.  Try this:

(if (or (featurep 'alsa-sound) (featurep 'native-sound))

Lennart Poettering pointed out on fedora-devel-list that this may be a
manifestation of this bug:

Comment 3 Jerry James 2008-01-14 12:13:07 EST
A workaround to this problem is to configure XEmacs with the following option:

This is probably a good change to make permanently in F8+ anyway, since it makes
XEmacs talk directly to the PulseAudio daemon.  I've been using an XEmacs
configured that way all day, and haven't had a single crash.
Comment 4 Ville Skyttä 2008-01-19 05:29:35 EST
Hm, I remember there's a long history of crash reports on xemacs-beta about
XEmacs and EsounD and AFAIU that's the reason why its autodetection is off by
default in XEmacs's build upstream; has something significant happened in this
area so that those crashes should no longer happen?
Comment 5 Jerry James 2008-01-20 16:23:06 EST
Yes, you are right.  However, any use of XEmacs' ALSA sound code in F8+ results
in an immediate crash every time.  I've been using the ESD code for several days
now without a single crash.  Also, those reports were against "real" ESD, not
PulseAudio-pretending-to-be-ESD, although that may not matter.
Comment 6 Ville Skyttä 2008-01-20 17:33:55 EST
Ok.  I tried to reproduce the crash with 21.5.28-5.fc8 on x86_64, KDE with aRts
enabled but all system sounds disabled, no pulseaudio, no esd, but failed. 
Could you give me an exact recipe how you can trigger the crash?  I applied your
init.el snippet from comment 2 and added a similar featurep for esd-sound for

Hitting Ctrl-G in a scratch buffer I can hear something (like cracks or the
like) from speakers, but there's no crash.  After configuring with
--with-sound=nonative,noalsa,esd there's no sound whatsoever anymore, but I
suppose that's because I don't have esd running nor pulseaudio enabled.
Comment 7 Jerry James 2008-01-22 14:02:22 EST
I'm using GNOME with xemacs-21.5.28-5.fc8.  I have access to two machines, one
i386 and one x86_64.  I get the same crash on both.  Using the comment 2
snippet, I can start XEmacs, press Ctrl-g, and get the reported crash.  These
are default Fedora 8 installs; I've done nothing to the sound settings since
installing.  Since this appears to be a PulseAudio bug, you'll have to be
running PulseAudio to get the crash.  We already know that "real" ALSA works. 
Thanks, Ville!
Comment 8 Alexandre Silva Lopes 2008-01-23 10:28:48 EST
You get this crash if you are using alsa-plugins-pulseaudio.
Comment 9 Bug Zapper 2008-11-26 03:22:38 EST
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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 '8'.

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 8'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 8 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: 
Comment 10 Bug Zapper 2009-01-09 00:11:17 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
