I'll look into getting the latest version of PA. My goal was to use PA as a replacement for esound server... I'd like to be able to record/mix different sound sources (midi, analog, sound from files (mp3, wav, ogg, etc)) and be able to create different file formats, including sound delivered in flash (I'm not a fan of flash as it consumes alot of cpu time, but it is in demand). I played with jackd for a while and was impressed with it's technical capabilities, but unfortunately, I haven't found a way to play flash sound through jackd... that is, flash in firefox. I found a how-to in the Ubuntu forum that seemed to patch together a solution the involved PA: <a href="http://ubuntu-utah.ubuntuforums.org/showthread.php?t=548178">http://ubuntu-utah.ubuntuforums.org/showthread.php?t=548178</a> and have run into configuration/version issues since. Question: PA, esound, jackd, etc.. are all called sound servers, implying that you can replace one with another... like apache vs iis.... is the main difference that they use different client/server communication protocols? So, the competition among the sound servers is really over the communication protocol... and it looks like sound performance/features is affected by the communication protocol.

You seem to have an older version of pulseaudio. Since 0.9.8 pulseaudio has supported 32-bit samples, so you'll have to upgrade to at least that version. An unrelated note: you seem to have made the decision to run pulseaudio as a system-wide daemon. That is not generally recommended way to run pulseaudio, it's only for the cases when the per-user way just doesn't cut it. This isn't a fatal mistake (if it's mistake at all, I don't know what kind of setup you actually have/need), and you don't necessarily need to fix it.
