Several sound-applications at the same time


On my fed.-box, it seems like some apps require to lock the sound-device, to have it just for itself. This makes the programs who want's this not to start (like alsaplayer and vlc). Other programs like play, kaboodle and xine can run together at the same time. This problem occured first when I enabled some event-sounds in kde3. Now alsaplayer won't start at all, and vlc gives no sound.

Im running alsa 1.0.4
alsaplayer 0.99.76
kde 3.1.4-4
vlc 0.7.1
Fedora core 1
Kernel 2.4.22-1.2115.nptl (not changed since installation)

What can I do to make the programs run together? Must I disable kde event sounds?

Thx for any help.

One thing you can do is, for every application that has an aRts output plugin, use it. That application will then be able to share the sound device with every other application that uses aRts. If alsaplayer has no aRts output plugin (it may well have one) then use xmms which definitely does have one (though you may need to install it), or noatun which uses aRts by default.

Another thing you can do is, go into the aRts configuration (you can find that in Configure KDE -> Sound System) and set it to not full-duplex. The aRts sound server is built to go idle after a user-preset time lapse, but if it is in full-duplex mode it will stay running forever.

Thx for the reply, it was very useful. Alsaplayer does not support arts, so I got a mp3-plugin for xmms instead, and it works well. I changed the delay in KDE control, so I can also run Alsaplayer without waiting too long. But when other sounds are tried to be played at the same time as alsaplayer is running, they are qued and are played after each other after alsaplayer exist. This is quite anoying, so I'm not using it until it get support for arts.

Thx again.
