# SDL2 audio for Linux. Replaces the cpal playback path on Linux only;
# cpal stays in use for Linux capture and Windows capture/playback.
# Apple platforms use direct VoiceProcessingIO AudioUnits. Rationale: the
# cpal Linux backend opens raw ALSA `default`, which on most Arch
# / Fedora / Debian installs routes through `dmix` + `plug` with
# nearest-neighbour resampling and very small period sizes — the
# combination produces audible crackling/popping. SDL2 on the same
# systems routes through PipeWire's PulseAudio compat bridge (or
# real PulseAudio), both of which carry a high-quality resampler
# and a sensible default period. The upstream tsclientlib audio
# example (`tsclientlib/examples/audio_utils/ts_to_audio.rs`) and
# the official Qint client both use SDL2 in exactly this shape;
# this dep brings Chanora in line with that pattern.
#
# `bundled` is OFF deliberately — we link against the system
# libSDL2.so. Arch ships `sdl2-compat`; Debian/Ubuntu ship
# `libsdl2-2.0-0`; Fedora ships `SDL2`. The chanora-flutter Linux
# build documentation lists this as a runtime dependency.
