Weapon fire (and ~all one-shots) played FOREVER: sf2extract flagged a sample as
looping whenever the SF2 shdr had loop points -- but almost every SoundFont sample
has loop points; whether to actually loop is the instrument's sampleModes generator
(igen oper 54): 0/2 = one-shot, 1 = loop, 3 = loop-until-release. The old heuristic
looped 239/241 samples, so SetupPatch set AL_LOOPING=1 on fire/explosion/step sounds.
Read sampleModes at the same igen zone as sampleID and loop only on 1/3. Now
166 one-shot / 75 loop: LaserAFire/BigExplosion/BasicClick -> ForceStatic (one-shot),
EnginePower/EngineMotor/coolant -> LoopAtWill (correctly sustained). Regenerated
audiopresets.cpp; the WAV PCM is unchanged.

Root cause of "no sound, ever": the two audio backend DLLs shipped in the repo
are fakes. libsndfile-1.dll exports 15 funcs BY ORDINAL ONLY (no names) and
sf_open() always returns NULL; OpenAL32.dll (72KB) imports only KERNEL32 -- no
dsound/wasapi/winmm -- so it is a pure no-op that returns fake handles
(ctx=0x00000001, alGenSources->0) and never touches the hardware. The whole
render->device->buffer->source->play chain ran clean and silent.
Fixes:
- OpenAL32.dll: replace the stub with the real OpenAL Soft 1.25.2 Win32 build
(imports AVRT/ole32/WINMM, real WASAPI backend). The exe imports the 25 AL
funcs by NAME so it is a drop-in; alGenSources now yields a live source and
alSourcePlay reaches AL_PLAYING.
- libsndfile: DROPPED entirely. It is replaced by LoadWavPCM() in L4AUDRES --
a tiny RIFF/WAVE fmt+data reader that loads our soundbank WAVs (16-bit PCM)
straight into the AL buffer. Removed the .lib/.dll from the link + copy and
git-rm'd the stub. (This also kills the "ordinal 50 could not be located in
libsndfile-1.dll" load-failure popup: adding an sf_strerror import bound to
an ordinal the 2..16-only stub could not satisfy.)
- Soundbank: 241 samples cracked from AUDIO1/2.RES (SF2 v1.0) by
tools/sf2extract.py into content/AUDIO/*.wav + the allPresets[2][128] table
(audiopresets.cpp), replacing the zero-init btstubs stub. All 241 now load
(alErr=0). BT_AUDIO_TEST plays buffer0 as proof-of-life; BT_AUDIO_LOG traces
the chain.
Remaining: in-game triggering (AudioEntities on fire/step/engine/explosion)
so PlayNote fires during play -- next audio wave.
