alsa-project/alsa-ucm-conf issue #774 was opened from EricLin0509:

## Summary

After upgrading the `alsa-ucm-conf` to `1.2.16`, the builtin speaker and microphone in MSI Prestige 16 Flip AI+ C3MTG has gone, and these devices previously worked fine. To make them work again I have to downgrade `alsa-ucm-conf` to `1.2.15.3` (keep `alsa-lib 1.2.16` is fine).

Similar issue #773

## Environment

- OS: Arch Linux
- Device: MSI Prestige 16 Flip AI+ C3MTG
- `alsa-ucm-conf` broken: 1.2.16-1
- `alsa-ucm-conf` working: 1.2.15.3-2
- Kernel: 7.0.11-1-cachyos
- Audio server: PipeWire 1.6.6 / WirePlumber 0.5.14

## Root cause

The configuration can't be loaded in version `1.2.16` on a board matching `rt713-sdca`

Here are the outputs of `alsaucm -c hw:0 dump text` in these two versions.

- 1.2.15.3
