I've it working! (do not have YET a web interface)
What I did:
1) created a new dag5 repository (because I'm on SME8b6).
If you're on SME7.x you need a common dag repository (change dag5 to dag and el5 to el4 on line below):
/sbin/e-smith/db yum_repositories set dag5 repository Name 'Dag - EL5' BaseURL 'http://apt.sw.be/redhat/el5/en/$basearch/dag' EnableGroups no GPGCheck yes GPGKey http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt Visible no Exclude freetype,htop,iptraf,rsync,syslinux status disabled
and tell yum to install it to me:
yum install mplayer --enablerepo=dag5(again, if you're on SME7, use dag instead of dag5)
after that, mplayer anysong.mp3 would play in your servers speakers.
I'm trying to install webmplayer interface on it now... more to came!
