[Bug] Audio DSP panic/IPC timeout on Lunar Lake-M (8086:a828) with CS42L43 codec

[spuctum]

System Info:

Hardware: Intel Lunar Lake-M, Dell Pro 14 Plus PB14250
OS: Pop!_OS
Kernel: 7.0.11-76070011-generic
Issue: The audio subsystem fails to initialize. aplay -l shows no soundcards. Kernel logs report DSP panic!, IPC timeout, and failed to create module drc.21.1.

Steps taken:

Updated firmware from upstream linux-firmware.
Tested with kernel parameters snd_intel_dspcfg.dsp_driver=1, snd_intel_dspcfg.dsp_driver=3.
Forced probe snd_sof_pci_intel_lnl.force_probe=8086:a828.
Result remains the same: Firmware loading fails with error -110.
Requesting assistance in debugging the drc.21.1 module initialization failure.

Thanks, Alice
