As @Teresa-e-Junior pointed out pactl is the tool to use:
First of all we might want to get the IDs of our PA sinks. On my system this is what I get:
$ pactl list short sinks
0 alsa_output.pci-0000_01_00.1.hdmi-surround module-alsa-card.c s16le 6ch 44100Hz SUSPENDED
1 alsa_output.pci-0000_00_1b.0.analog-stereo module-alsa-card.c ...

I'm not exactly sure what you meant with "ALSA or PulseAudio", I assume you meant PulseAudio over ALSA. I'm also in the dark, in regards to your distribution, so I'm prevented from being very specific. If you provide your distro + version, I can let you know if this problem has known workarounds. GNU/Linux audio has improved, but it's not on level with ...

The -t option needs to come before the filename it applies to. Also, -t pulse means to read directly from (or write to) the PulseAudio daemon; it's not a file format as such. The type name for raw audio is raw.
Try this:
parec ... | sox -t raw -b 16 -e signed -c 2 -r 44100 - hmm.ogg ...
(where ... means to keep the same arguments you had before)

I finally found a solution to this, it took me a while to find so I post it here in case it might help others.
Edit the file:
/etc/pulse/default.pa
Look for the line:
load-module module-udev-detect
And change it into:
load-module module-udev-detect ignore_dB=1

I use:
cvlc --no-one-instance --volume 150 <soundfile>
to play short sounds (< 1 second) as notifiers for program activities.
The --no-one-instance makes sure this playing does not get scheduled after something that might be running in my 'normal' vlc (like music) and which is setup to have a single instance and for which additional invocations ...

If I understand correctly, you want playback on your build in sondcard and capture (microphone) from external USB device.
Your external device is listed as card 2: device 0 and your build in soundcard as card 0: device 0
I think your asound.conf should look something like this:
pcm.!default
{
playback.pcm
{
type hw
card 0
device 0
}

Just a guess but something like this in a file systemd/user/pulseaudio.service:
[Unit]
Description=PulseAudio Sound System
Before=sound.target
[Service]
BusName=org.pulseaudio.Server
ExecStart=/usr/bin/pulseaudio
Restart=always
[Install]
WantedBy=session.target
I found this in a github repo which had additional files related to systemd setup.

They are actually similar in being sound servers. JACK is designed for real-time/low-latency response, which is required by professional-level audio solutions. PulseAudio is targeted more at general desktop (where less strict needs apply). PA seems to be heavier than JACK - being more complex induces more overhead. On Linux both use ALSA for real output in ...

The following commands are use to manipulate the PulseAudio sound server:
pacmd - Used to reconfigure a PulseAudio sound server during runtime.
pactl - Used to control a running PulseAudio sound server.
Here are some examples of how they function.
pacmd list-sinks :: list name or index number of possible sinks
pacmd set-default-sink [sinkname] :: set ...

PulseAudio has got a command line interface. You can read about it on the official wiki.
You didn't mention witch distro You use, but with the default package manager it should be easy to search after the PulseAudio CLI package.
Basically you search the command which does the job for You, then You can create an alias command in Your ~/.bash_profile or ...

It seems like I found a solution, at least for this particular case.
Since I knew the card and device number assigned by ALSA, I just had to open /etc/pulse/default.pa. in editor and change this line
#load-module module-alsa-sink
into this
load-module module-alsa-sink device=hw:2,7
where 2 and 7 are my particular instances of card and device numbers.

Remember that Alsa is not removed when installing Pulseaudio. Pulseaudio uses Alsa in quite some extent and you could say it's a layer on top of Alsa.
There's pavucontrol (on Debian/Ubuntu also the package name). It allows you to do a little bit more configuration on the Pulseaudio server and Pulseaudio-managed things like Bluetooth audio profile selection. ...

These are not services, but compile options, use ./configure --enable-XXX to enable them (see ./configure --help first)
Also, to alter compile options for debian based distros, consider the debian way,
First use apt-get source XXX to fetch the source code, and use apt-get build-dep XXX to install dependencies,
Afterwards, change the debian/control file ...

In this case the card is always the same. What is changing between a switch and another is the "card-profile".
So the solution which actually worked is:
pacmd set-card-profile <cardindex> <profilename>
In my case I found all the card profiles with:
pacmd list-cards
And after I can switch between monitor and laptop speakers with:
pacmd ...

Your sinks will all have a property you can use to figure this out -- device.bus_path and sysfs.path. You can examine these with pactl list sinks.
In the ideal world, your USB devices will all have unique serial numbers which you can see in the device.serial property, which would allow you to identify the device regardless of the port it's plugged in to. ...

Realtek ALC887 (HDA Intel) in Wheezy ?

1) When you try ldconfig -v: will be in this list libasound_module_conf_pulse.so library?
2) You can try command strace -f -F -o alsamixer.strace alsamixer, and then explore file alsamixer.strace and try to go from bottom to top and find, why it cannot open file with library.

arecord will record from your sound card, which is a dummy, so its not surprising it contains rubbish. You want to record from the network. There are lots of ways to do that, but snd-dummy won't help. You could try pulse-audio - it has good support for network sound, or you could use jack audio - a bit harder to set-up, but less confusing and low latency.

The basis of the problem is you have to change which sound card is being used. How to do this depends on whether you are using a gui or something else. I know next to nothing about pulse audio so I can't help with directions directly for that. But if you're using KDE you can open your "K" menu -> system settings -> multimedia -> phonon -> Audio Hardware ...

I recently encountered this issue in one of our computer labs running CentOS 6. I was able to make Pulse show up and work for the roaming profile user by adding them to the pulse and pulse-access groups. This didn't even require a relog, audio just magically started working when I did this.
This seems to only apply to the local user-- that is, the changes ...

I don't know if this question is still relevant to you since its so old, but its been upvoted 3 times, so I guess I should point out that the standard gnome applet is for alsa. You can get a pulse applet here:
http://code.google.com/p/gnome-pulse-applet/
Just install and go, have fun.
