Root cause of the residual jitter (correlating with framerate, per real-hardware testing): this project never overrides PSP_MAIN_THREAD_PRIORITY, so the main/render thread runs at PSPSDK's default of 32. A pthread created with default attributes (as thread_t/threadStartRequest does) runs at priority 60 - numerically higher, meaning LOWER scheduling priority on PSP's inverted scale. Under load the feeder thread was structurally guaranteed to lose scheduling contention to the main thread, starving the hardware channel's double buffer and producing audible jitter that worsens exactly when frames get slower - confirmed via disassembling PSPSDK's precompiled pthread glue (pte_osThreadGetDefaultPriority returns 60) rather than guessing. audioStreamPSPThreadFeed now self-prioritizes via sceKernelChangeThreadPriority(sceKernelGetThreadId(), 18) as the first thing it does, matching the elevated-priority pattern PSP SDK samples use for their own timing-sensitive auxiliary threads.
