Sound always stuck 100% in gnome


I have a new Lenovo Yoga Pro 7 gen 9 14APH9. I installed debian bookworm.
I have the sound block at 100%. I can do no sound with the slider at 0 but impossible to change to the level selected.
Always 0 or 100%.

Kernel 6.7 (backports).
Type of card : family 17h/19h hd audio controller

I have try with alsa and it’s the same.

Any idea ?
