Pulseaudio has never worked for me in X11

[hakonrk]

One of the first things I do when installing Fedora is to remove pulseaudio. For some reason, it never works for me in X11.

Until now, I've been content with removing it altogether, since it's not giving me anything I need, only problems. Unfortunately, now I have to develop some software that needs to work with pulseaudio, and so I need to be able to use it myself.

I have spent a lot of time trying to figure out why it doesn't work, but I have made no progress. Here's what I know:

• My system boots into runlevel 3 (text mode)
• Pulseaudio works fine in the text console
• If I start X.org with "startx", pulseaudio still works, but only when I swap back to the console with Ctrl-Shift-F<n>
• If I try to play audio (e.g., aplay test.wav) when X has the screen, the program trying to play audio will block forever without a peep in the speakers

Any tips on how to fix this would be greatly appreciated. It is a complete mystery to me why it works for everybody else I know, but never on any of my four computers, all the way back to Fedora 8.

It is one of the biggest mysteries. It did not work for me until F-10, and suddenly it started working.

Appending tsched=0 to the line load-module module-hal-detect in /etc/pulse/default.pa fixed it for me - thank you very much!

Still, I have to wonder: Why does all my systems fail without tsched=0, and why are seemingly everyone else unaffected? All my systems have completely different hardware, so it makes no sense.
