Quick playback tests (non-destructive)
================================================================================
Note: if ALSA 'pulse' PCM is missing, do NOT use: speaker-test -D pulse
Try these instead (they use PipeWire):
Tip: these are wrapped with a short timeout to avoid hanging.
(uses: timeout -k 1s 5s ... -> TERM then KILL)
$ timeout -k 1s 5s speaker-test -D pipewire -c2 -t sine -f 440 -l 1

Hints
================================================================================
- If HDMI ports show "not available", verify cable/monitor input/EDID and re-plug.
- If profile keeps reverting after reboot, compare:
- ~/.local/state/wireplumber/default-profile
- /usr/share/wireplumber/main.lua.d/60-kaisa-ucm.lua (device.profile)
- any *kaisa* snippets under ~/.config/wireplumber/ or /etc/wireplumber/
- If set_hw_params errors appear in logs for a given pcm (2/3/4), test only ONE HDMI at a time and switch sink accordingly.
