Pulseaudio Setup independant on a X-Server installation

Make sure you add your username to the following system groups:

pulse, pulse-access, audio.

sudo nano -w /etc/group

Example for the user dl6kbg:

audio:x:29:pulse,dl6kbg
pulse:x:119:dl6kbg
pulse-access:x:120:dl6kbg

sudo nano /etc/default/pulseaudio

change settings to:

PULSEAUDIO_SYSTEM_START=1
DISALLOW_MODULE_LOADING=0

sudo nano /etc/pulse/system.pa

and add:

load-module module-native-protocol-tcp auth-anonymous=1

Restart pulseaudio:

sudo /etc/init.d/pulseaudio restart

or restart the system and fire up the softrock server. Pulseaudio runs now in systemwide mode and your softrock server should be able to establish a connection to your following dspserver.

In order to use 96000 or 192000, you will need to configure pulse audio by editing:

/etc/pulse/daemon.conf

Uncomment these settings and change it for your needs.

Example:

default-sample-format = s24le
default-sample-rate = 192000

For realtime audio add the following to:

/etc/security/limits.conf

@audio - rtprio 99
@audio - memlock unlimited

and reboot and enjoy your system.
