Disable pulseaudio in Ubuntu 9.04

According to [Ubuntu 9.04 Jaunty – Keeping the beast Pulseaudio at bay] by idyllictux, you can disable (not remove) pulseaudio in Ubuntu 9.04, so that you can use ALSA or OSS for some sakes. As for my sake, my two PCs around got problems using pulseaudio. One was that when I played music via Cmus, there were some sudden audio hangs and system hangs every now and then. It bothered a lot because sometimes it also blocked the usages of all input/output devices! (keyboard, mouse, and often X itself) But I cannot be sure if it resulted from pulseaudio. The other was that I got pure noises playing audio/video in my Ubuntu since a reboot after a kernel upgrade. It happened since last Friday, which also (I cannot be sure, either) caused my PC to hang during the weekends, and I lost two stages’ records of Tour de France 2009 on channel FMTV. It was a miserable thing to me.

Well, after I disabled pulseaudio on my two sets of Ubuntu 9.04 today, I found the above problems gone, at least for longer than 3 hours. I hope this solved the problem, and probably yours too, by trying to fall back on ALSA.
