duffyduck 20050d4077 release: bump version to 0.0.8.8 2026-05-10 14:12:59 +02:00
duffyduck 79760d1b2e fix(audio): kurze TTS-Texte spielen wieder ab — AudioTrack-Buffer entkoppelt von Preroll
OnePlus A12 stallte bei kurzem Text mit pos=0/34112: 336KB Buffer fuer
3.5s Preroll, aber nur 68KB Daten drin → AudioTrack faehrt nicht an.

Fix: Buffer fest auf ~2s, plus play()-Retry bei pos=0 nach 500ms.
