Bug#445165: gnome-core: Gnome locks audio device.
Rafael
Version: 1:2.14.3.6
Severity: important
When gnome session is started, audio device is locked, and meny aplications cannot play sounds, only Gnome and Gnome aplicatios emit sounds.
For example, before start Gnome, i can play a WAV audio file with aplay command, but after gnome is started i cannot play sound with aplay, in gnome and in tty console i
obtain this error:
ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
aplay: main:545: audio open error: Device or resource busy.
The result is that many other aplications as aMSN, amarok (this give also Device busy error), and videos from youtube doesn't sound, but media files played with totem
sound, and also sound tests located in System -> Preferences -> Sound.
Thanks.

This is because you have enabled ESD, in System -> Preferences -> Sound.
If your sound driver doesn't allow device sharing, only applications
using ESD will be able to play sound when it is started.

Did you enable the sound server in GNOME? If yes, then you should
configure your application to use "Esound" as audio output.
Alternatively, you can disable the sound server and configure your
applications to use "Alsa" directly.
Another option which I'm using is to setup PulseAudio, that works like
esound and supports alsa apps as well, but requires more work to setup.

then Gnome events doesn't sound. I am sure than i had ESD activated and
other aplications could sound in previous Debian Lenny/Sid development
state, in addiction i have comfirmed that in others distributions (for
example Ubuntu 7.10), i have activated ESD and both Gnome events and
other aplications sound without problems, because this, i think that
there is a bug in Debian.
I have right now updated Debian Sid with Gnome 2.20 and the problem
continues.
Thanks for your atention.

You must configure your other applications to use ESD if you decide to
enable it and your sound card doesn't support device sharing.
Otherwise the behavior you are describing is expected.
