ROG Flow Z13 2025 Audio fix

ROG Flow Z13 2025 (ai max 395) Audio Fix

Disclaimer: I don't know much about kernel development, this fix was figured out with AI assistance.
My problem was that the speakers work but are way quieter than Windows. Kernel logs show:

cs35l41-hda: Falling back to default firmware.

The fix is simple: copy-paste the ROG Ally entry with a different device ID. It solves the audio problem subjectively (we're far from amazing sound, but at least twice as loud).

vimdiff cheat sheet

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
