Upon installing Fedora 12 on my desktop I had experienced Audio skipping and scratches when playing DVD’s on Totem, but have experienced no other audio issues with playing music, flash, or avi and mpeg files in Totem. I set out to find a solution to this problem. I do not know how much of a difference any of the below processes made because in the end I lost audio playback in Totem altogether, and ended up Installing VLC. If you are having similar problem I recommend installing VLC first, and work backwards from there.

as root:

alsactl init 0

add tsched=0 to /etc/pulse/default.pa

remove pulseaudio as root



yum remove pulseaudio

reinstall with the fallowing as root:



yum install pulseaudio alsa-plugins-pulseaudio pulseaudio-esound-compat pulseaudio-libs pulseaudio-libs-glib2 pulseaudio-module-zeroconf pulseaudio-libs-zeroconf xmms-pulse pulseaudio-module-gconf wine-pulseaudio xine-lib-pulseaudio pulseaudio-utils pulseaudio-module-bluetooth gst-mixer padevchooser paman paprefs pavucontrol pavumeter

now edit /etc/pulse/default.pa

replace: load-module module-detect

with: load-module module-hal-detect tsched=0

open /etc/pulse/daemon.conf

replace: ; default-fragment-size-msec = 25

with: ; default-fragment-size-msec = 10

and reboot

check your audio mixer settings. Open the Pulse Audio Device Chooser (loads in system tray) and select default as the default server.

At this point DVD would have audio in Totem on the menu system but not when playing the movie. At this point I got frustrated enough with fixing DVD audio in totem I defaulted to installing VLC.

as root:

yum install VLC

As always VLC works perfectly. I prefer Totem (with the Xine engine), however it appears as if Fedora no longer provides this option. The only real issue I have with VLC is its use of QT libraries when I prefer to run GTK libraries for the simple fact that I run the XFCE desktop with some Gnome components and QT adds extra unnecessary weight to my desktop.
