Listen on the Scarlett, because the fifine returns silence (V-487) 99e73ea653

mavwaked has logged zero completed utterances in three days of journal, and
the wake word is not why: the count was zero before it existed too. The fifine
returns RMS 0.00004 over five seconds with its capture switch on and its ALSA
volume at the full 496 of 496, so the silence is in the hardware and no flag
reaches it.

Measured over eight seconds of the same speech: fifine 0.00004, onboard ALC897
0.142 clipping at peak 1.0, USB camera 0.289 clipping, Scarlett Solo 0.003
clean. The two loud ones clip, so the quiet clean one wins.

Named CARD=Gen rather than card 4, because a USB card number moves when
something else is replugged and this daemon must not change ears quietly.

Verified in the room: keyword heard at score 0.999, utterance complete in
1.65s, and she answered "сейчас 17 часов 24 минуты".
