AriaCast

• 1.1.9 This release rewrites the AirPlay 1 and AirPlay 2 senders from the ground up and adds real Google Cast support. It also includes a batch of discovery, DLNA and plugin-sandbox fixes.
• AirPlay 1 (RAOP) - rewritten Fixed: encrypted streams never worked - the AirPort RSA public key was wrong, and the AES tail block was padded instead of sent in the clear. Fixed: audio was announced as L16 while ALAC frames were sent, so receivers played noise; the codec now follows the receiver's cn (ALAC, or real L16 PCM). Fixed: the et/cn TXT lists (e.g. 0,3,5) were misread; full TXT records now reach the client. Fixed: metadata lacked the mlit container and RTP-Info; text, artwork and progress are now delivered according to the receiver's md. New: RTP is paced on a single monotonic clock with sync packets every second, a jitter buffer with inaudible drift correction, and retransmission of lost packets. New: password-protected receivers (Digest auth), Apple TV on-screen-code pairing, MFi auth-setup, Apple-Challenge verification, keep-alives with automatic reconnect, FLUSH on pause, mute, and a proper TEARDOWN. AirPlay 2 - rewritten Fixed: transient pairing omitted the transient flag, and nothing after pairing was encrypted; the RTSP control channel and the event channel now use HomeKit session encryption. Fixed: 48 kHz audio was sent as 44.1 kHz (slow, drifting playback); it's now resampled. New: PIN pairing (/pair-pin-start, full pair-setup) with stored credentials and pair-verify on later connections; access-control passwords. New: NTP timing for Apple receivers, PTP where the device allows it, and automatic fallback to AirPlay 1 for PTP-only receivers (e.g. shairport-sync). New: DMAP metadata, artwork and progress, /feedback keep-alives, retransmission, event-channel volume/command handling, stream + session TEARDOWN. Google Cast - new Real Cast protocol (CastV2 over TLS) replacing the DIAL launch attempts that didn't work on current devices: launches the Default Media Receiv
