How can one build an empty dummy package for pulseaudio?

Well, the output of the following command is ( look for the two errors ):
$ pacman -Q libao libpulse lib32-libpulse pulseaudio pulseaudio-alsa
audacity libao
libao 1.2.0-1
libpulse 5.0-1
lib32-libpulse 5.0-1
error: package 'pulseaudio' was not found
error: package 'pulseaudio-alsa' was not found
audacity 2.0.6-1
libao 1.2.0-1
but the output of the following command is ( the pulseaudio and
pulseaudio-alsa packages are there! ):
$ pacman -Ss pulse
extra/libao 1.2.0-1 [installed]

extra/libcanberra-pulse 0.30-4

I don't understand why these two packages was not found:
'pulseaudio' and 'pulseaudio-alsa' was not found?
So when I run
$ pacman -Qi pulseaudio
I get
error: package 'pulseaudio' was not found

When I run this command I get:
$ cat /etc/modprobe.d/alsa-base.conf
options snd slots=snd_hda_intel,snd_usb_audio
options snd_hda_intel index=0
options snd_usb_audio index=-2

Yes, I did reboot after removing pulseaudio and setting up ALSA.
Audacity can't started at all.
I solve the audacity problem by reinstalling audacity package.
Now I can run audacity.

When if I launch Jackd before starting Audacity I can select between
ALSA, OSS and Jack Audio Connection Kit too:
when Jackd selected, there are:
playback device: system ( and that option is available only )
recording device: system ( and that option is available only )
and this recording device is in my webcam ( I know this because I
haven't any other microphone and with it I can racord my voice in
audacity ),
when ALSA selected, there are three options:
playback device: HDA NVidia: ALC883 Digital (hw:0,1)
playback device: iec958
playback device: spdif
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Front Mic:0
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Rear Mic:0
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Line:0
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Front Mic:1
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Rear Mic:1
recording device: HDA NVidia: ALC883 Analog (hw:0,0): Line:1
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Front Mic:0
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Rear Mic:0
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Line:0
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Front Mic:1
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Rear Mic:1
recording device: HDA NVidia: ALC883 Alt Analog (hw:0,2): Line:1
sysdefault: Front Mic:0
sysdefault: Rear Mic:0
sysdefault: Line:0
sysdefault: Front Mic:1
sysdefault: Rear Mic:1
sysdefault: Line:1
and none of these recording devices works in audacity.
What I did to setup ALSA on my system are followings:
did run asoundconf-gtk and get files:
~/.asoundrc.asoundconf
and
~/.asoundrc ( probably because I can't remember whether create it
manually after run of asoundconf-gtk ? )
Content of my ~/.asoundrc file is:
# Include settings that are under the control of asoundconf(1).
# (To disable these settings, comment out this line.)
</home/cspal/.asoundrc.asoundconf>
pcm.!default {
type plug
slave.pcm {
@func getenv
vars [ ALSAPCM ]
default "hw:NVidia"
}
}
pcm.usb
{
type hw
card U0x46d0x808
}
pcm.!default
{
type asym
playback.pcm
{
type plug
slave.pcm "dmix"
}
capture.pcm
{
type plug
slave.pcm "usb"
}
}
Content of my /etc/asound.conf file is:
pcm.!default {
type plug
slave.pcm {
@func getenv
vars [ ALSAPCM ]
default "hw:NVidia"
}
}
ctl.equal {
type equal;
}
pcm.plugequal {
type equal;
# Modify the line below if you do not
# want to use sound card 0.
#slave.pcm "plughw:0,0";
# by default we want to play from more sources at time:
slave.pcm "plug:dmix";
}
# pcm.equal {
# If you do not want the equalizer to be your
# default soundcard comment the following
# line and uncomment the above line. (You can
# choose it as the output device by addressing
# it with specific apps,eg mpg123 -a equal 06.Back_In_Black.mp3)
pcm.!default {
type plug;
slave.pcm plugequal;
}
Now when I record ( I have running Jackd already ) my desktop with
Qt-recordMyDesktop I can select record device in it: system:capture_1
( there are no other capture devices out there ). I suppose this
device is the microphone of my webcam.
But, when I play the recorded video I can't hear my voice there. Why?
