  "message": "audio_device: enforce the documented FIFO minimum in the EP-IN flow-control guard\n\nThe comment above audiod_tx_packet_size() states flow control needs a FIFO\nof at least 4*Navg, but the guard tests nominal_size[1] \u003c\u003d fifo_depth * 4 -\ntrue for any FIFO larger than a quarter packet - instead of\nnominal_size[1] * 4 \u003c\u003d fifo_depth. As written, flow control engages on\nFIFOs far below its own documented minimum, where the depth/2 setpoint sits\nwithin one packet of empty and the packet_size \u003d 0 branch (a zero-length\npacket, i.e. an audible 1 ms dropout for audio-class hosts) is reachable\nfrom ordinary scheduling jitter rather than only from gross clock\ndeviation. With the guard corrected, undersized FIFOs fall back to the\nplain min(count, max) path as intended.\n",
