Captures the TV's audio and sends it out over several transports. The
primary one is HyperHDR: RTP/L16 to a host-side loopback device, since
HyperHDR has no network audio input of its own. A second route renders
the spectrum on the TV and sends FlatBuffers images to port 19400
instead, for setups where touching the host's sound config is not an
option.
native/ the service: capture backends (PulseAudio, ALSA, exec,
test tone, all dlopen-based), DSP, and one file per sink
frontend/ D-pad driven UI at a fixed 1920x1080
servicefiles/ native service manifest plus the boot script
host/ RTP receiver and the loopback installer for the HyperHDR
machine
tools/ build/package, asset generation, Homebrew Channel
manifest, on-TV probe
test/ host-side suites: FlatBuffers and RTP verified against
real decoders, the engine end to end, the page in jsdom
