 Each `jack` stream creates a separate connection to a jack server and registers
 as many input ports as there are audio channels in this stream (according to
-`sampleformat`). The timing information is taken from the Jack server, so all
-streams connected to the same Jack server should play perfectly in sync.

 You can use `autoconnect` to automatically connect this streams input ports
 with Jack output ports. The parameter takes a regular expression and matches
 against the whole Jack port name (including client name). For example, if you
 have a Jack client named "system" with four output ports ("playback_1",
 "playback_2", ...) and you want each output as a separate SnapCast stream, you
-could either autoconnect to the exact ports, or you use a autoconnect search term
-that returns all ports and use `autoconnect_skip` to pick the right one:
