After 45 the game was silent in two places: message windows had no voice-over, and the title had no music. A helper agent ported both into piney-audio (commit 088f107), checked against the game's own code; the details are in the voice page and the sound page. This entry puts them in the runtime.

What the runtime now asks for

Each mode hands its requests to piney-game, which passes them to the sound driver:

• Voice lines. Every message window the scripts open asks for ccEvVoiceRequest(event, msg). The camera tutorial's prompts ask with event 3, as the game does. The save's Voiceover option (+0x842c) and parody flag (+0x842b) are read at each request, so changing the option in OPTION takes effect on the next line.
• Stopping a line. ccEvVoiceStop comes from three places: a camera tutorial prompt closing, the scripts' sound command 7, and the desktop's own message windows.
• The title's music. ccSetupDemo turns all sound off and loads the title's bank (ccSndSQLoad(7)). The title's ccSqPlay, ccSqStop, ccSqFade and ccSetMainVol now reach it; before, they were only printed.
• Changing mode. ccGame::ChangeRequest calls ccSound::gameInterrupt, and each mode's setup starts with ccAllSoundOff.

Timing

With the logos and the intro stream counted as played, the title's music starts at frame 74, when LogoMain calls ccSqPlay(0). New Game fades it over 8 frames. The first setup line's voice (event 1, message 1) is asked for two frames after the change to the desktop.

Also: texel bleed at sprite edges

Commit 63635fb fixed the text glitches seen when moving the cursor. Sprite UVs sat exactly on texel boundaries, and the GPU sampled the neighbouring glyph or icon there. A 1/512 texel bias now makes it pick the texel the GS picks. Text areas now match the CPU GS model.

Checked

setup_lines_are_voiced runs the session from power-on with a headless Audio, doing what the window loop does each frame: handle the requests, frame(), then render one frame of samples. Two checks:

• The title's music sounds in more than 90 of the 95 frames between ccSqPlay(0) and New Game's fade.
• Channel 0 streams event 1's lines for more than 60 frames of the setup.

piney-game has 5 tests, all passing; clippy and fmt are clean.
