Jste si to rozhodil.

Jsou dvě možnosti buď nebudete používat pulseaudio a vše budete hnát
přes alsu na které rozběhnete dmix (u nových stačí smazat konfigurák alsy).

A nebo si musíte spravit to pulse audio a potom používat pulseaudio
místo alsy.

Co používají vaše programy?

Co máte v /etc/asound.conf ?

Já tam mám:

 [petr na nt /etc]$ cat asound.conf
 #
 # Place your global alsa-lib configuration here...
 #

 @hooks [
 	{
 		func load
 		files [
 			"/etc/alsa/pulse-default.conf"
 		]
 		errors false
 	}
 ]

A v /etc/alsa/pulse-default.conf

[petr na nt ~]$ cat /etc/alsa/pulse-default.conf
# PulseAudio plugin configuration
# $Id: pulse-default.conf,v 1.3 2008/03/09 15:50:49 lkundrak Exp $

# Let's create a virtual device "pulse" for mixer and PCM

pcm.pulse {
    type pulse
    hint {
        description "PulseAudio Sound Server"
    }
}

ctl.pulse {
    type pulse
    hint {
        description "PulseAudio Sound Server"
    }
}

# Let's make it the default!

pcm.!default {
    type pulse
    hint {
        description "Default"
    }
}

ctl.!default {
    type pulse
    hint {
        description "Default"
    }
}
