 Good way to start a post asking for support!

 99.99% of the time, sound problems with PA result from a poorly configured
 default system. Distros have traditionally done a pretty poor job at
 integrating PA and Ubuntu is probably the worst offender, but are
 thankfully beginning to improve.

 I'd suggest you try a live CD from other distros to see if the problem
 will be the same there. As the person responsible for sound integration on
 Mandriva and as a release has just been made, I can only recommend trying
 a "Mandriva One" flavour of your choice:
 http://torrent.mandriva.com/public/2010.0/

 Failing that, the general order of things is:
  1. Ensure that pure alsa is working: {{{pasuspender -- aplay -Dhw:0,0
 /usr/share/sounds/startup3.wav}}} If this doesn't work the problem is
 unrelated to PulseAudio.
  2. If ALSA works, then check the Output Devices tab in pavucontrol. If it
 says "Dummy Output" or similar it means that another application is
 hogging the sound device and PA cannot use it. You can find out which
 application is hogging the device via {{{fuser /dev/dsp}}} and {{{fuser
 /dev/snd/*}}} commands.
  3. If your real sound card shows up in pavucontrol's Output Devices tab,
 then check the "Configuration" tab and ensure the correct profile is used.

 Lastly, the configuration and handling of ALSA mixers is a very tricky and
 error prone business. Users almost always do not know what the various
 sliders and controls in the ALSA mixers actually do and getting sound
 working is usually a matter of tweaking everything and eventually getting
 sound output! This is far from ideal and PA is trying to rationalise that
 and hide everything from users, but due to the massive amount of different
 hardware out there, we cannot cover all bases and need user feedback to
 solve these problems and improve the situation for everyone. This is how
 free software works and it's is expected of users who participate in the
 free software ecosystem to provide this kind of feed back and appreciate
 the development model without getting upset or angry.

 So if the above does not help you, please provide the output from:
  1. {{{pulseaudio -k; pulseaudio -vvvvv}}} (run as a single command and
 you may have to repeat it a few times to get past the "PID file" error due
 to the system trying to automatically respawn PA for you).
  2. When PulseAudio is running the output from {{{pacmd ls}}}
