PROBLEM: Why does Gizmo Project block sound in SUSE?

SOLUTION: Gizmo Project is a free VOIP software that works with SUSE Linux too! Yet, the problem is that it is using an obsolete sound system called OSS (Open Sound System). To make it work with your other programs in piping sound, you need to "trick" it to use the new sound system called ALSA (Advanced Linux Sound Architecture). In order to "trick" it, you must have an /etc/asound.conf file in your computer. Below is a copy of my asound.conf.

EXAMPLE: This is an /etc/asound.conf file; please copy and paste it:

pcm.asymed {
type asym
playback.pcm "dmix"
capture.pcm "dsnoop"
}
pcm.!default {
type plug
slave.pcm "asymed"
}
pcm.!dmix {
type dmix
ipc_key 1024
ipc_key_add_uid yes
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
rate 48000
}
bindings {
0 0
1 1
}
}
pcm.!dsnoop {
type dsnoop
ipc_key 5778293
ipc_key_add_uid yes
slave {
pcm "hw:0,0"
period_time 0
period_size 128
buffer_size 2048
format S16_LE
rate 48000
}
}

ENVIRONMENT: SUSE Linux 9.3+
Gizmo Project 1.0.0 (build 17)+
ALSA 1.0.10+
