I am trying to get an Airport Express working with Amarok on a desktop running
Slackware 13.1 x86_64. I first got it working piping mpg123 output to
JustePort.exe, so I know there's no hardware problems. I wanted to try to
get it to work with Amarok. I read a bunch of threads and did finally
get raop_play to compile and install. I can start it up fine.
I thought I was almost done....

This blog is my primary source of information:

http://www.jroller.com/nwinkler/entry/a ... rt_express

about how to configure Amarok to use it with the Airport Express, but
I can't figure it out. I have installed raop_play in the kernel, and if I then
start Amarok, and go to Settings -> Configure Amarok. there is "Engine" option.
I continued to Playback -> Configure Phonon. Amarok shows 3 choices for
"Output Device Preference for the 'Music' Category":

HDA Intel Analog
HDA Intel Digital
Esound

If I run "amarok --version", I get this:

Qt: 4.6.2
KDE Development Platform: 4.4.3 (KDE 4.4.3)
Amarok: 2.3.0

I can't see any way to configure Alsa as was done with older versions of Amarok.
Does anyone have raop_play working with a new version of Amarok, and if so, how did
you configure Amarok?

no idea but the version of Amarok the example is running is the 1.x series and that is why you're not seeing the "engine" option, remember the article is from 2006.

actually all that you are running is a bit old - Amarok is at 2.3 (with the 2.4 version due soon) and Kde is at 4.5.4 (with 4.6rc1 being tested).

if what you need to do is be able to configure the xine backend to get it to work then you can try to manually edit the xine config file found in ~/.xine, might me that the old Amarok xine screen was just a gui for editing this file

Phonon stores it's Xine configuration seperately in ~/.config/kde.org/phonon-xine.conf
