Multi-source sound

Ephracis · 12-31-2004, 01:48 AM

When i use XMMS, i also want to use other sound sources, at the same time i hear the music. Like continueing to hear the music while i still here the sound from amsn. I've tried the arts and esound soundservers and i don't like the delay they give to every sound.

you can use alsa dmix plugin.
http://alsa.opensrc.org/index.php?page=DmixPlugin
heres my ~/.asoundrc

Code:

pcm.!default {
    type plug
    slave.pcm "dmixer"
}
 
pcm.dsp0 {
    type plug
    slave.pcm "dmixer"
}
 
pcm.dmixer  {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:0,0"
        period_time 0
        period_size 1024
        buffer_size 32768
        #periods 128
        #rate 44100
    }
    bindings {
        0 0
        1 1
    }
}
 
ctl.mixer0 {
    type hw
    card 0
}

in xmms output configuration select ALSA, audio device - default and be sure to deselect mmap mode in advanced tab.
and for amsn select aplay for sound command(if it has such option).
and you should be able to hear notifications while xmms is playing.

Thank you.

Will it work for every program or just the one who supports it?

for any program that can use ALSA for sound output
