AFAIK skype requires pulseaudio. I'm using plain ALSA or jackd. The OP
might need pulseaudio, if getting sound from several desktop
applications at the same time is wanted, without taking care about
another sound server, such as jackd, or using another alternative such
as dmix.

I assume it was not intended to send it off-list:

pulseaudio -k

And to start it, pulseaudio --start

On my Ubuntu 14.4, the control panel applet for sound contains nothing 
unless pulseaudio is running.  I also discovered that firefox needs the 
proper card configured in the applet, but once that is done, pulse
audio is not needed to run.

Other applications may need pulse audio to produce sound altogether.

I agree, for troubleshooting purpose disabling pulseaudio is a good
idea. I don't know how to do this, but likely the link provided by
Chris explains how to do this. AFAIK how to disable pulseaudio could
depend on the used version of pulseaudio.

Ralf

100% I agreement with you. That is why I suggested this approach since it
is simple and might help further diagnose the problem.

Again 100% in agreement with you.

It's just an easy thing to try, Ralf. If the card works under this scenario
too then some info is gained. If the card doesn't work, then only a minute
has been lost but the idea that Pulse is the culprit is a little less
believable.

Seems to me that going to the effort of trying to remove Pulse is a bit
premature, as you note below.

My point exactly.

The OP is in an difficult situation. He wants to do a bunch of things; he
isn't completely sure how as yet, because he can't get the most basic thing
working.

If it seems like I was contradicting you, I was not. I composed my response
and pushed send while your email was in the process of arriving.

1.

We don not know if pulseaudio is the culprit.

2.

Even if we should know that it is the culprit, depending on the OP's
needs, it might be wiser to fix the issue and to use pulseaudio.

3.

Assuming regarding the OP needs it should be better to get rid of
pulseaudio, then it would be idiotic to disable it, instead of removing
it completely. Why should somebody disable it, if it's completely
unwanted? If I don't need a package, I don't install it. If something I
should need, works without it, but has got a hard dependency to it, I
simply build an empty dumm package.

Any evidence for the below claim?

"Removing or purging PulseAudio from a Ubuntu system can break other
installed software and potentially cause errors and broken
dependencies."

This is just a claim without explanation. As already pointed out, just
replace it by a dummy package, you even don't need to recompile
software.

If needed I could explain how to build a DEB dummy package and how to
build an Arch Linux dummy package. I'm using them since pulseaudio does
exist without ever experiencing an issue.

But again, removing pulseaudio might not what the OP wants? It's just a
_possibilities_ that pulseaudio is the culprit for the issues, nobody
mentions that it's the cause for the issues.

Ralf

Please read the following

http://kodi.wiki/view/PulseAudio/HOW-TO:_Disable_PulseAudio_and_use_ALSA_(without_removing_PulseAudio)_for_Ubuntu

It explains why and how to disable pulse rather than uninstall it.

Actually we need to know what you exactly want to do, with audio. Sure,
assuming your GNOME desktop should have got a hard dependency to
pulseaudio, it most likely would be enough to replace it, with an empty
dummy package, to get rid of pulseaudio. Getting rid of pulseaudio
might not solve your issue and depending on your needs, you might want
to use pulseaudio.

Did you already sent a request to a support channel of the distro you
are using? IOW did you ask on a distro related forum or mailing list?

Ralf

Hi.
Is there a way to remove pulse audio then and just use alsa?
If so I can use my soundcard without having to buy Another one.

Two of several possibilities

1. No pulseaudio

2. Randomly it becomes the default hw:0 at startup, without an
   alsa-base.conf to ensure this.

[rocketmouse@archlinux ~]$ cat /etc/modprobe.d/alsa-base.conf 
# ALSA module ordering
options snd slots=snd_hdspm,snd_ice1712,snd_ice1712
