Thank you Raymond,

'esd'. I wrote in
https://launchpad.net/distros/ubuntu/+source/alsa-lib/+bug/26483:
{
With the present setup (default Ubuntu), if 'esd' is not running ('killall
esd'), applications do not cause alsa to output 'ALSA lib pcm_dmix.c:802:
(snd_pcm_dmix_open) unable to open slave' to $HOME/.xsession-errors.
}
This confirms the name I gave this bug: "Ubuntu5.10 not configured for
Alsa"
It is good to know the reason for the error messages but It does not help
me in any way. If would rather have the error messages than stop 'esd'.
Best regards,
Manolo.

Gnome/Multimedia_System_Selector:
Default Sink
Output: ALSA - Advanced Linux Sound Architecture
Pipeline: alsasink
Default Source
Input: ALSA - Advanced Linux Sound Architecture
Pipeline: alsarc
But Gnome starts and uses 'esd' as well as most applications.
