bug#4208: 23.1; play-sound-file does not work

[Tom Tromey]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


I'm using Emacs 23 on Fedora 11.

play-sound-file reliably does not work for me.  When I try it I get this
error:

play-sound: No usable sound device driver found

I don't know why this fails.

I looked at the code a tiny bit.  I think one possible fix would be to
write a PulseAudio sound back end for Emacs.  PulseAudio seems to be the
current way of producing sounds on Fedora.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

This error shows up when Emacs tries to open the old OSS based sound device.
This isn't surprising if pulseaudio is running.
But you should be able to use ALSA instead.  But this message indicates that 
HAVE_ALSA isn't defined.  Have you installed ALSA development libraries?  The 
package is called libasound2-dev or something similar.  Redo the configure and
make sure it says (early in the configure run):

checking for alsa >= 1.0.0... yes
checking ALSA_CFLAGS... -I/usr/include/alsa
checking ALSA_LIBS... -lasound


Also try
% aplay <soundfile>

where <soundfile> is some file.  If it works you have ALSA and Emacs should 
use that.

Well, one can set up pulseaudio so ALSA doesn't work.  On the other hand one 
can set up ALSA to use pulseaudio.  I don't know how Fedora 11 does it.

Thanks.

I'm just using the Fedora RPM, so I don't know.
I'll report it to the Fedora Emacs maintainer, perhaps it is just a
missing BuildRequires.

Yes, this works.

Looks like.

checking for alsa >= 1.0.0... no
