Ugly hack department.I have problems with skips and pops when I play audio files (OGG) with Kaboodle. IIUC, Kaboodle uses the aRts Daemon (artsd) to output sound.
I find that if I set the 'nice' for all instances of 'artsd' to -10 that I have no problems -- the sound is perfect even when doing something with the window manager -- except that sometimes playing sound locks the screen.
Setting the 'nice' for X to -8 seems to fix that problem.
You can select the 'nice' for X in "$KDEDIR/share/config/kdm/Xservers":
:0 local@tty1 /bin/nice -n -8 /usr/X11R6/bin/X vt7 -deferglyphs 16 -br -dpi 100
Is there any way to select the 'nice' for the aRts Daemon?
Currently I have to do this with a script, a DeskTop icon, and KDEsu.
It would also be nice [:-D] to be able to set the 'nice' for TiMIDIty since it
also needs the high priority to work without skips and pops.
This appears to fix the problem.
I attach a modified version of: "$KDEDIR/share/config/kdm/Xstartup"
and a script: "$KDEDIR/share/config/kdm/Music" to add to that directory (must be executable).
NOTE: change the paths to fit your system.
NOTE: you must have: "/sbin/pidof" for this to work.
NOTE: I have also modified my: "$KDEDIR/share/config/kdm/Xservers" file (as previously stated) to avoid (or improve) a slight problem with music locking the screen.
