ROG Flow Z13 2025 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).
