I haven't tested with a 32 bit system. I'm not sure if I will get the
time for that. I don't think in this case it has much to do with the
kernel. I think it is because pulse is compiled for 64 bit and the apps
are looking for 32 bit libs.

Well, there's your problem. It's great that you try out new
software though, but of course then you'll get more stability
issues as well.

To clarify, I have found that is difficult to get 32 bit apps to
connect to a
64 bit build of pulseaudio but these apps don't cause stability issues
with pulse. The problem is they just don't connect. I can still run
them directly over the alsa layer but that locks the device in a
standard Fedora 11 setup. I believe this would affect alot of "normal"
users so I would like to find a workable solution that can be
recommended to all packagers as a LAD standard.<br>
<br>
I am finding stability issues with 64 bit apps connecting to a 64 bit
build of pulseaudio when it is connected to a 64 bit build of jack
which uses 64 bit alsa libs on a standard 64 bit kernel. I don;t have
stability issues with jack when pulse is not being used. I have run
jack for days on this machine.<br>
<br>
In my testing I have found that pulseaudio is unstable when using 64
bit apps. I have found that it is very difficult to get apps built for
32 bit environments to play nicely with pulse audio on a standard
Fedora 11 setup even when I have the 32 bit pulse libs installed.<br>
<br>
One annoying issue is libflashplayer that seems to be hard coded to
search in /usr/lib instead of /usr/lib64. This causes conflicts with
apps like realplayer and skype which are looking for the 32 bit libs in
/usr/lib/alsa-lib. In order to get libflashplayer to run through pulse
I had to link the 64 bit pulse-alsa libs from /usr/lib64/alsa-lib to
/usr/lib/alsa-lib.<br>
<br>
The instability could also be related to running a standard kernel not
rt kernel. Although this machine is powerful enough to run hundreds of
audio streams asynchronously so I don't think it is a hardware issue.<br>
