For Round 5, I have updated pulseaudio to the latest dev version.
pulseaudio 0.9.16-test4-7-gaa74
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- This time round I can successfully load the pulse
module-jack-sink/source and play totem through pulseaudio+jack.
System load when playing totem goes up to around 20% which seems kind of
high but nothing like it would need to lock things up.
However I after about 15 minutes the jack source and sinks disappeared
and running "pulseaudio -k" returns with
E: main.c: Failed to kill daemon: No such process
This seems to be related to looking at the "Sound Preferences" dialog.
As it has happened a couple of times now.
Restarting pulseaudio brings both sink and source back and I can resume
playing with totem.
So it would appear that there are some stability issues with the
pulseaudio jack modules, gnome-volume-control and or pulseaudio.
- Testing skype returns with "problem with audio playback" if the
outputs are set to pulse so that is fairly annoying.
Running from the commandline I get this when I make a test call:
======================================
$ skype
ALSA lib control.c:874:(snd_ctl_open_conf) Cannot open shared library
/usr/lib/alsa-lib/libasound_module_ctl_pulse.so

ALSA lib pcm.c:2171:(snd_pcm_open_conf) Cannot open shared library
/usr/lib/alsa-lib/libasound_module_pcm_pulse.so
======================================
Seems to be library related as pulse is installed in /usr/lib64/ by
default. Skype is looking for the 32 bit libs. Figure there must be a
workaround for that one.
I run "yum install alsa-plugins-pulseaudio.i586" then skype doesn't
complain about problem with audio playback.
Instead I get these messages:
============
socket(): Address family not supported by protocol
ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect:
Connection refused
============
So I remove alsa-plugins-pulseaudio.i586
Now I try linking the /usr/lib64 module library to the /usr/lib folder
ln -s /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so
/usr/lib/alsa-lib/
This doesn't work either. I see the same "Cannot open shared library..."
messages in the terminal.
So it looks like we need a workable solution for running skype with
pulseaudio on a 64 bit platform.
===================================
* Skype
You can just visit Skype's site and click on the Fedora 7 package.
Select to open it with 'Package Installer (Default) and you are done.
Alternatively you can install the Skype repository. Open a terminal and
type:
su -c 'gedit /etc/yum.repos.d/skype.repo'
In that file copy the following lines:
[skype]
name=Skype Repository
baseurl=http://download.skype.com/linux/repos/fedora/updates/i586/
enabled=1
gpgkey=http://www.skype.com/products/skype/linux/rpm-public-key.asc
gpgcheck=0
Now you can easily install/update skype by typing:
su -c 'yum install skype'
su -c 'yum update skype'
===================================
Also tried "usermod -a -G pulse user" where "user" is the name of the
user who needs to use skype.
Still no luck.

Winner: Jack and Pulse Audio. Pulse still a little unstable but mostly
working nicely with jack.
Looser. Skype. If I want to use Skype I have to turn off jack. However
if I get a usb phone then my problem is solved as I could set it as the
Skype device and use my onboard device for jack+pulse audio.
Conclusion.
Pulse Audio and Jack will work together if running pulseaudio v 0.9.16
or greater.
Just remember to
1: pulseaudio -k
2: start jack
3: puseaudio -D -nF ~/jackd.pa
Or add the above commands to the qjackctl config panel.
