HP OmniBook Ultra Flip (Lunar Lake, 103C:8CDE) — ALSA headphone jack state changes but audio does not route to headphones

alsa-project/alsa-ucm-conf issue #758 was edited from pavlo0909:

### Description

On the HP OmniBook Ultra Flip (Intel Lunar Lake), headphone plug/unplug is correctly detected by ALSA, but audio does not route to the headphone output automatically.

When headphones are inserted, the `Headphone Jack` control changes state correctly. However, the active output does not switch to headphones in KDE / PipeWire, and audio continues through the internal speakers. The internal speakers and internal DMIC both work normally.

### Environment

- **Manufacturer / Model:** HP OmniBook Ultra Flip Laptop 14-fh0xxx
- **Platform:** Intel Lunar Lake (LNL)
- **Codec:** Realtek ALC245
- **PCI SSID:** 103C:8CDE
- **Distribution:** Fedora 44 (KDE Plasma Desktop Edition)
- **Kernel:** 6.19.14-300.fc44.x86_64
- **Audio stack:** SOF + PipeWire + WirePlumber

### Diagnostic Results

I verified headphone jack detection at the ALSA level using:
`watch "amixer -c0 contents | grep -A2 Jack"`

The control `numid=19,iface=CARD,name='Headphone Jack'` changes state correctly:
- **Unplugged:** `values=off`
- **Plugged:** `values=on`

### Observed Behavior
- ALSA detects headphone insertion correctly, but the desktop environment (PipeWire/WirePlumber) does not automatically switch the routing or expose the port correctly.
- Audio continues through internal speakers.
- **Key Observation:** Enabling ALSA `Auto-Mute Mode` manually via `amixer -c0 set 'Auto-Mute Mode' Enabled` resolves the issue immediately (internal speakers mute and audio routes to the headphones). This suggests the UCM configuration is missing the proper jack/verb mapping for this specific hardware SSID.

### Technical Details (from alsa-info)
- **Headphone node:** `Node 0x21 [Pin Complex]`
- **Pin default:** `0x03211020: [Jack] HP Out at Ext Left`
- **Topology:** `intel/sof-ipc4-tplg/sof-hda-generic-2ch.tplg`

### Request
Could you check whether this hardware requires a dedicated UCM configuration or specific JackControl/mapping for PCI SSID `103C:8CDE` to allow PipeWire to manage the switching without relying on the hardware Auto-Mute control?

**Note to Maintainers:** I have attached the full `alsa-info.txt` to this issue. This hardware was previously discussed in the SOF project (issue #5757) where it was confirmed that HDA jack detection is functional at the driver level.
