Bug Description

Hi

I have installed Ubuntu and do an upgrade after the first install.
Then it seems i have the 1943 Bug, so i do the "gconftool-2 -s -t bool
/schemas/desktop/gnome/sound/event_sounds false" command.
After i could open a session, but i haven't a /dev/dsp device.
I have 2 sound cards a c-Media on borad and a Sb on a pci slot :

When i launch XMMS it works fine, i have the music, but with Rhythmbox i have
nothing !!!
XMMS use this out-plugin : ALSA 1.2.10
So i launch gstreamer-properties for configuring Alsa ( someone tail me that
Rhythmbox use gstreamer ) but sometimes i have an error when testing and
sometimes not
For me the is a very big problem, Xmms said Alsa, but gstreamer seems to can't
working with !!!!!

Then i launch :

Why Xmms work and not Events and Rhythmbox ? Is it possible to configure Events
and Rhythmbox for using the same driver than Xmms ?

/dev/dsp is created automatically by the snd-pcm-oss module via udev. Please
send the output of the following, immediately after a reboot:

ls -l /dev/dsp
ls -l /dev/snd
dpkg -l udev
ps aux | grep udev
grep udev /var/log/syslog

Have you made any changes to the module loading configuration, or anything else
which may be preventing it from working correctly?

OK, so the log shows that /dev/dsp is being created exactly as it should be.
Perhaps something is removing it? What changes have you made to the system
which could be having an effect? This works perfectly in every Ubuntu
installation I have tried.

Ok i think i found where is the problem.

There is 2 cards on the PC : the first cmipci (card 0) on the motherboard the
second SB!Live (card 1) on a pci slot
XMMS use a direct address for playing ( hw:1,0 )
Rhythmbox don't use something like this and it play on the card 0 which is not use

Even if t's strange for me, it seems that there is no need of a /dev/dsp for
playing on the card, but the question is how could i do for that Rhythmbox play
on the card 1 ?

Bingo; this is the problem. Perhaps you ran alsaconf at some point?
