The 'buffer' mode in Baileys' downloadMediaMessage() silently returns an empty buffer for audio/voice messages (PTT, OGG Opus), while images download correctly. Switching to 'stream' mode and collecting chunks manually resolves the issue. Tested in production (WAHA Plus 2026.3.4, NOWEB engine, S3 storage): - Before: voice messages saved as 0 bytes in S3 - After: voice messages saved with correct size (58,005 bytes confirmed) Fixes devlikeapro#1996
