I've spent some time looking into this today, but my Debian installs are on
the other machine, and the sound card is an Audigy2 soundblaster, which is
capable of multiple audio streams, so I've been looking at the problem on my
FC2 install, with an earlier version of KDE.
First regarding SDL. I installed the relevant SDL packages on FC2 so I could
play an SDL based game, and I've just looked on Debian Etch, and have
installed it also on there for some reason or other. The packages installed
are.
libsdl-image1.2
libsdl-mixer1.2
libsdl-ttf2.0-0
libsdl1.2debian
libsdl1.2debian-oss
I have the alsa-oss package installed, so the above package doesn't create any
problems, as the alsa-oss package provides an Alsa emulation layer to apps
that need to use OSS.
I do not have libsdl-sound1.2, or libsdl-net1.2 installed.
I can't remember why I installed the SDL stuff. That was when my Etch was
still Sarge, and is probably for some audio app that I installed.
I don't believe there is any problem in leaving those SDL libraries installed,
as they should only be called on when you run an app that requires them.
btw. Is dosemu working for you?
It's worth installing the alsa-oss package, as if you have any OSS audio apps
that you want to use, they will then work.
Getting back to KDE, aRts, and Noatun.
Noatun will play a .ogg music file irrespective of whether the check box in
Controlcentre/sound and multimedia/sound system is checked or not.
Now I do have a one liner in a file named .asoundrc in /home user, and it
doesn't matter now if that check box is checked or not. I can play a tune
using Noatun, and play another tune using MhWaveedit at the same time.
The one liner is below with instructions.
Noatun, and playing cd's. I didn't know it could do that. Anyway, when I put a
CD in the drive on Etch, I get a bit of activity showing on the drive, but
nothing on the desktop. I then open cdplayer, and the CD is showing there
with the title of the CD. Then pressing play, just plays the CD. I have seen
this sort of multiple choice thing when inserting a CD on Fedora Core 5
though. Btw. I don't though have kaffeine installed, so perhaps it behaves
differently then.
Another thing to look at is /etc/group , and see if you as user are on the
cdrom group. IIRC I put myself on that, as before doing so I could only play
CD's when logged into the desktop as root.
Here's the one liner.
First create a file in your /home/user directory named .asoundrc . Then add
the following line to the file, highlight, and paste, whatever.
pcm.dsp0 { type plug slave.pcm "dmix" }
Save it, and close the file. Seriously I don't know if this will fix any of
your problems, but now I can have the checkbox in KDE's control centre/sound
and multimedia/soundsystem checked without causing problems with other music
apps.
Can't think of much more to say at the moment.
Nigel.
