Root cause of the silent-alarm-on-HDMI bug, measured on the host rather than
inferred:
$ pactl list cards | grep 'alsa_card.pci-0000_01_00.1' -A1
Active Profile: off
$ pactl list short sinks
61 alsa_output.pci-0000_0d_00.6.analog-stereo IDLE
While that card's profile is "off" the G27Q's HDMI sink does not exist, so
_list_real_sinks() cannot return it. _play_on_all_sinks re-enumerates sinks
every beep cycle -- its docstring says it picks up late outputs "without
re-running activation" -- but that can never find a sink whose card is off.
There is nothing to enumerate.
Activation runs exactly once, at startup. At wake time the monitor has not
finished its HDMI handshake, the profile reads "available: no",
_parse_profile_line drops it, and the card is never revisited. Silent alarm.
_reactivate re-runs activation on a decaying schedule (3,5,7,10,15,20,30s)
on a daemon thread, logging the full enumerated sink list every pass so the
next failure is diagnosable from the JSONL log instead of guessed at.
Verified end to end on this machine:
BEFORE: ['alsa_output.pci-0000_0d_00.6.analog-stereo']
AFTER : ['alsa_output.pci-0000_01_00.1.hdmi-stereo',
'alsa_output.pci-0000_0d_00.6.analog-stereo']
and a 1 kHz tone plays through the HDMI sink (paplay exit 0). Note the
constant ALARM_AUDIO_SINK was correct all along; only the activation was
failing.
Wiring into WakeAlarm lands with the _alarm.py split, since touching that
478-line file trips the 250-line gate.
399 tests, 100% branch coverage.
