 Hi Christian, 

 Yes, the sound will be passing through 2 sound servers if and only if ARts
was already running for the current user (i.e. if it's gnome app started from
KDE menu trying to play something) during esd startup. This shouldn't add any
noticable delay in sound playback of course. If no ARts was started for
current user when ESD was started, the sound will be passing only through one
sound server (esd) - as it always was before applying the patch.

 Best regards,
