After my little issue with the kernel oops I decided to make sure my
system was fully upto date. I ran yum update and got a new kernel as
part of the update.
1: pulseaudio -k
2: pulseaudio -D
3: Notice that the gnome volume icon is displaying as muted.
4: Adjust the volume setting and unmute check box but icon doesn't
change and the slider is still set to mute when I check it.
5: Open gnome-volume-control (Sound Preferences)
6: Set output volume to not mute, raise volume level to full. Gnome
volume icon still showing mute. Oh well.
3: Test a song with totem. Success. Audio plays fine.
Next phase:
1: Pause Totem. Verify that the audio stream disappears from the
Applications tab in (Sound Preferences) panel
2: pulseaudio -k
3: qjackctl
4: press start and jackd starts playing
5: Restart pulse audio with the following command
pulseaudio -D -n -F ~/jackd.pa (* see below for script)
6: Pulse i/o's show up in qjackctl connections panel
7: System load is stable at < 10%
8: Check already running "Sound Preferences" ui to see if the jack i/o's
show up. Nothing.
9: Restart "Sound Preferences". Notice that pulse output has disappeared
from qjackctl connections. Input is still working. Can also see the jack
source in the input tab in "Sound Preferences".
10: Restart "Sound Preferences". Pulse input disappears from qjackctl
input connections.
11: pulseaudio -k
12: pulseaudio -D -nF ~/jackd.pa
13: Pulse Audio input reappears in qjackctl input connections panel. No
output. jack-source shows in the "Sound Preferences" input panel. No
jack-sink in the output panel.
14: Volume icon still muted...
Winner: Jack.
High points to Pulse for trying to interface. Unstable results. Possibly
due to bugs in gnome-volume-control or the pulse audio jack modules.
Linux version 2.6.29.6-217.2.3.fc11.x86_64
jack - 0.116.1
pulse audio - 0.9.15
Qt: 4.5.2
QjackCtl: 0.3.4
gnome-volume-control 2.26.0
Ding. Time out for Round 5. Next round let's update Pulse Audio to the
latest dev version.
(*) ~/jackd.pa
Basically a copy of /etc/pulse/default.pa but with module-jack-sink and
module-jack-source defined

### Automatically restore the volume of streams and devices
load-module module-device-restore
load-module module-stream-restore
### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
#load-module module-alsa-sink
#load-module module-alsa-source device=hw:1,0

source_name=input
#load-module module-null-sink
#load-module module-pipe-sink
load-module module-jack-sink

### Automatically load driver modules depending on the hardware available
.ifexists module-hal-detect.so
load-module module-hal-detect
.else
### Alternatively use the static hardware detection module (for systems that
### lack HAL support)
load-module module-detect
.endif
### Automatically load driver modules for Bluetooth hardware
#.ifexists module-bluetooth-discover.so
#load-module module-bluetooth-discover
#.endif
### Load several protocols
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif
load-module module-native-protocol-unix
### Network access (may be configured with paprefs, so leave this commented
### here if you plan to use paprefs)
#load-module module-esound-protocol-tcp
#load-module module-native-protocol-tcp
#load-module module-zeroconf-publish
### Load the RTP reciever module (also configured via paprefs, see above)
#load-module module-rtp-recv
### Load the RTP sender module (also configured via paprefs, see above)
#load-module module-null-sink sink_name=rtp format=s16be channels=2
rate=44100 description="RTP Multicast Sink"
#load-module module-rtp-send source=rtp.monitor
### Automatically restore the default sink/source when changed by the
user during runtime
load-module module-default-device-restore
### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams
### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.
load-module module-console-kit
### Enable positioned event sounds
load-module module-position-event-sounds
### Load additional modules from GConf settings. This can be configured
with the paprefs tool.
### Please keep in mind that the modules configured by paprefs might
conflict with manually
### loaded modules.
.ifexists module-gconf.so
.nofail
load-module module-gconf
.fail
.endif
# X11 modules should not be started from default.pa so that one daemon
# can be shared by multiple sessions.
### Load X11 bell module
#load-module module-x11-bell sample=bell-windowing-system
### Register ourselves in the X11 session manager
#load-module module-x11-xsmp
### Publish connection data in the X11 root window
#.ifexists module-x11-publish.so
#.nofail
