Dear Maintainer,

I recently upgraded to Trixie from Bookworm and audio stopped to work.

On Debian 13 (Trixie), audio doesn't work properly with Intel SOF devices (e.g., sof-hda-dsp).
Manually installing the `firmware-sof-signed` package version 2025.05-1 from Sid completely resolves the issue.
I suggest considering integrating this version into Trixie stable or preparing an official backport.

the outcome of this action:

After installing the firmware-sof-signed package version 2025.05-1 from Debian Sid on a system running Debian Trixie (stable), the audio issue affecting Intel SOF devices (e.g. sof-hda-dsp) was resolved.
The system correctly detected the audio hardware, and playback/recording functionality was restored.

outcome expectation:

I expected the audio to work out-of-the-box on Debian Trixie using the default firmware-sof-signed package available in the stable repository.
Instead, the default version did not support the hardware properly, resulting in missing or non-functional audio devices.
