Session sanity (THIS OFTEN EXPLAINS 'no sound')

================================================================================

If you run this as root / without a logged-in desktop session:
- systemctl --user will be offline
- /run/user/$UID may not exist
- PipeWire/WirePlumber won't be running
- ALSA may show 'no soundcards found'

Current:

$ bash -lc echo "USER=$USER UID=$UID HOME=$HOME XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR-}"
USER=jack UID=1000 HOME=/home/jack XDG_RUNTIME_DIR=/run/user/1000

VERIFY mode (more detailed validation)

[NOTE] This runs active route + playback attempts and captures kernel error windows.

[NOTE] Best run right after boot and BEFORE any manual --fix, to catch first-open races.

Kernel hints (SOF/HDMI hw_params IPC errors)

================================================================================

Note: if you see PipeWire 'set_hw_params: Input/output error', the real cause is often in kernel logs.
      This section tries to summarize SOF/ASoC HDMI failures (e.g. ipc tx error -5 for pcm2 HDMI1).

[WARN] Kernel log shows SOF/ASoC HDMI failures (tail):

[NOTE] then this is a kernel/SOF issue (not UCM/WirePlumber). Capture full: journalctl -k -b | grep -nE 'sof-audio|ipc tx error|pcm2|HDMI1'

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)

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.
