Every existing HyperHDR route replaces whatever else is on the LEDs:
routes 1/2 hand HyperHDR's own audio effect a device to read, route 3
sends a synthetic spectrum image, and both take over via HyperHDR's
priority system. For a setup that already has a real colour source
(a screen grabber, a USB capture card) feeding an ambilight-style LED
run, none of that is what's wanted -- the colour should stay put and
only brightness should react.
Read HyperHDR's own source (sources/api/JSONRPC_schema/schema-adjustment.json)
rather than guess: "adjustment" is a post-processing command with a
scaleOutput parameter (0-2.0) that applies regardless of which
priority is currently active. Confirmed the wire format too --
sources/jsonserver/JsonClientConnection.cpp frames it as plain
newline-delimited JSON over TCP (default port 19444), nothing like the
length-prefixed Flatbuffers protocol the visualiser sink speaks, and
with no handshake or registration needed before the first write.
sink_hyperhdr_adjust.c sends only that: no image, no priority, so it
never competes with an existing grabber. Non-blocking connect with the
same poll()+SO_ERROR pattern net/hyperion.c already uses, reconnects
every 5s, rate-limited to 20 Hz (a HyperHDR command every audio block
would be pointless flooding), and resets scaleOutput to 1.0 on close
rather than leaving the LEDs stuck at whatever it last sent. Cross-
compiles clean under -Wall -Wextra on the real webOS toolchain.
Wired through the same path every other sink follows: registered in
sink.c/sink.h, defaults in config.c, fields in frontend/js/app.js
(SINK_FIELDS/SINK_HELP), mock.js and ui_smoke.js updated for the new
sink card. Bumped to 1.0.3.

The device-source parser assumed pactl list short sources is strictly
tab-separated, true for stock PulseAudio but not guaranteed for a
TV's own heavily customized audio stack (this one names sources
tpcm_output/tpmedia/tptts/... — clearly not vanilla). A different
separator would have silently produced zero parsed sources with no
error, and the picker's own `when` guard would then just hide the row
entirely rather than show anything broken. Split on any whitespace
run instead of a literal tab; source names never contain embedded
whitespace, so this is strictly more permissive with no new failure
mode. Confirmed end to end on real hardware: tptts.monitor lit up
during the accessibility voice guide and reached HyperHDR.
Also: the System panel now shows the app's actual running version,
read from a <meta> tag substituted at package time (tools/build.sh
stage()) from frontend/appinfo.json — not hand-maintained, so it can't
drift from what was actually built. Requested after a version bump
alone wasn't enough to tell whether a reinstall had truly picked up
new files versus served something cached along the way; this settles
that question by inspection instead of by inference. Bumped to 1.0.2.

Every rebuild since 1.0.0 kept the same version, so the ipk filename
and repo.json content never changed even though the contents did --
indistinguishable from a stale cache to both Homebrew Channel's
update check and any HTTP cache sitting between the release and the
TV. Bumping the version changes the ipk's filename outright, which
sidesteps that ambiguity regardless of what's caching what.

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.
