Hi, It's required for some instances of PlayObject (especially video) to be able to determine the aRts server latency. I couldn't find any detailed information on this subject, but I'm currently using the following code. Arts::SoundServer server = Arts::Reference( "global:Arts_SoundServer" ); audio.latency = (unsigned long)server.serverBufferTime(); Is it safe to assume that there is only one aRts server? Is there a better way to determine the latency of the aRts server? TIA. bye, ewald >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
