esd doesn't have any timing information. If you want to use mplayer
remotely on an esd server with lip-sync audio, then you won't have
much success.

PA has a module "module-esound-sink" which you can use to create a
virtual sink that sends all data to a local or remote esd sink.

Please note however, that esd is a mess, don't use it. No timing, no
nothing. Bad stuff. YMMV.
