[pulseaudio-discuss] [PATCH v6 18/37] raop: Prefer ALAC encoding to raw PCM if supported by server

[Hajime Fujita]

From: Martin Blanchard <tchaik at gmx.com>

ALAC encoding is to be prefered simply because ALAC audio packet reverse-
engineering and implementation is in better shape than raw PCM. Sending ALAC
audio does not mean compressing audio and thus linking an external library to
do so. ALAC packets has the ability to carry uncompressed PCM frames, and
that's what is implemented at the time.
