 On an AirPlay-2-capable Shairport Sync, if you need offer only the older "classic" AirPlay (sometimes called AirPlay 1) service, set \fB--service-type=classic\f1. A potential use of this would be for Apple Music on Windows, which is not compatible with the AirPlay 2 service offered by Shairport Sync, but which is compatible with the classic-only service. To offer AirPlay 2 service only, set \fB--service-type=airplay2\f1 (note that this requires NQPTP). Set \fB--service-type=auto\f1 to allow Shairport Sync to choose AirPlay 2 service if NQPTP is present or classic AirPlay service if not, with "(Classic)" appended to the default service name.

 \fB-S \f1\fImode\f1\fB | --stuffing=\f1\fImode\f1
 Interpolate ("stuff") the audio stream using the \fImode\f1. "Stuffing" refers to the process of adding or removing frames of audio to or from the stream sent to the output device in order to keep it synchronised with the player. The \fBvernier\f1 mode is normally almost completely inaudible and suitable for low-powered devices. An alternative mode, \fBsoxr\f1, is less obtrusive but requires much more processing power. For this mode, support for \fBlibsoxr\f1, the SoX Resampler Library, must be selected when \fBshairport-sync\f1 is built. The \fBbasic\f1 mode is also suitable for low-powered device, but \fBvernier\f1 is better. The default setting, \fBauto\f1, allows Shairport Sync to choose \fBsoxr\f1 mode if the system is powerful enough.
