Bug 475904

Hi, I don't know WyabdcRealPeopleTTS sound library, but could you play sound with that on your system?

WyabdcRealPeopleTTS is an english speech library, it is composed of thousands of *.wav file. stardict can utilize this speech library to read words in english. Audio in my system works fine, I just can't hear any sound in stardict, is this something related to esound ?

I reach the same problems on x86_64. And I gets some warning messages from the log:

Hi alsa-oss maint.,

Just wondering if this is alsa-oss bug? as first line of error log mentioned?

  hi, I have a new clue to this problem.
  When I start stardict from terminal, I saw the following lines among the log messages:

Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 924
Expression 'ValidateParameters( outputParameters, hostApi, StreamDirection_Out )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1142
Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 924
Expression 'ValidateParameters( outputParameters, hostApi, StreamDirection_Out )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1142

  maybe this will help to solve this problem.

This is a very annoying issue. I can't live with a dic which is not able to play sound.

hi,
The error messages mentioned in comment #3 and #5 seems disappears, right?
But still no sound in stardict.
It seems that the gnome_sound_play() in src/desktop.cpp, play_wav_file(), doesn't play the wav files.

Which package are the gnome_sound_play() in src/desktop.cpp and play_wav_file() located?

(In reply to comment #8)
> Which package are the gnome_sound_play() in src/desktop.cpp and play_wav_file()
> located?

They are in stardict package. They are functions of stardict.

A little while ago there was a post on fedora-list:
https://www.redhat.com/archives/fedora-list/2009-February/msg00016.html

------------------------------------------------------------------
hi Great list,

I just find that the libgnome-2.24.1-7.fc10 has been disabled "esd" when it is built.
This has caused the "gnome_sound_play()" doesn't work and some package such as
"stardict" cannot play sound.

Why should we disable esd in libgnome? Could we enable it?
-------------------------------------------------------------------

So the problem is that libgnome tries to use OSS for sound output rather than libesd. The former does not work with PulseAudio, the latter does.

any news now?

Let's talk about a patch on the BBS or ML
http://bbs.fedora-zh.org/showthread.php?t=1082

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  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 '10'.

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 10'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 10 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Anyone want to fix this?

Is it still broken in f11 and f12

It is freezes at the splash screen on Fedora 12.

I am trying to debug it now.

The following tracker also mentioning about the problem from pulseaudio which
may be the source of problems of espeak:

*** Bug 512190 has been marked as a duplicate of this bug. ***

Check bug# 512190. I am rebuilding with espeak disabled for instance.

1. this is not related to the original report at all, and 2. disabling espeak support makes no sense, this needs to be sorted out in espeak. (But the easiest solution for those hitting that issue is to simply install PulseAudio.)

And here's a proposed fix for the espeak issue: https://bugzilla.redhat.com/show_bug.cgi?id=512190#c11
