Comment:
I don't like this Bugzilla: No obvious way to delete/edit comments; Big
fonts and short lines; Weird auto formatting causes havoc on
indentations; Anybody there?
I post again previous comment hoping it will be more legible this time:
I don't know if I made a mistake when, in my previous comment, I reported:
'using Ubuntu5.10 distribution packages for both kernel and Alsa ....
applications using AlsaSurround51Device don't cause alsa to output error
messages to .xsession-errors'. I have updated linux-image and now, with
linux-image 2.6.12-10-686-smp, version 2.6.12-10.26 and alsa-base 1.0.9b-4, all
applications using Alsa device 'surround51', while playing, cause Alsa to
output continuously: 'ALSA lib pcm_dmix.c:802:(snd_pcm_dmix_open) unable to
open slave' to $HOME/.xsession-errors. Applications checked:
aplay -Dsurround51 File.wav
#Error messages to .xsession-errors with 2 or 6 channels File.wav.
xmms File.wav
#Config: OutputPlugin:Alsa;AudioDevice:surround51.
#Error messages to .xsession-errors with 2 or 6 channels File.wav.
xine File.avi
#Config: audio-driver alsa;SpeakerArrangement:Surround5.1
#Error messages to .xsession-errors only if File.avi has 5.1 audio.
mplayer File.avi
#Options: '-ao alsa:device=surround51 -channels 6'
# or '-ao alsa -af surround -channels 6'
#Error messages to .xsession-errors with 2 or 6 channels File.avi.
I have found the reason some applications behave differently when launched from
GnomePanel or gnome-terminal is that the sound device '/dev/dsp' remains
closed, for Alsa surround51 device, for about 7 seconds after an application is
launched. Gnome-terminal has already been running for more than 7 seconds when
the sound application is invoked and it starts right away. Example:
-Launch gnome-terminal
-Type 'aplay -Dsurround51 File.wav'#Sound plays immediately.
-RightClick on GnomePanel. Select '+ Add to Panel'.
Select 'Custom Application Launcher'
-'Create Launcher window'/Command:'aplay -Dsurround51 File.wav'
-Click on created Gnome launcher. #Sound plays after 7 seconds.
If you write a shell script with
{
#! /bin/bash
until >/dev/dsp
do
sleep 1
done 2>&
audacity
}
and invoke it from a Gnome launcher, Audacity starts, after 7 seconds, without
any error message even if 'esd' is runnin (No other sound application should be
running or audacity will never start).
