HP Pavilion 14-ce3xxx (ALC295) – mute LED does not work in Linux

[lakshyaelite]

Laptop: HP Pavilion Laptop 14-ce3xxx
SKU: 172V6PA#ACJ
Audio codec: Realtek ALC295
Kernel: 6.17.0-20-generic
OS: Linux Mint 22.3 (Ubuntu-based)

Problem

The audio mute key works correctly, but the red mute LED on the keyboard never lights up.

The LED works correctly in Windows, so the hardware itself is functional.

What happens in Linux

• Pressing the mute key mutes/unmutes audio normally.
• The mute LED does not turn on when muted.

Notes

• hda::mute LED device exists but does not control the physical LED.
• The LED worked correctly when the laptop was running Windows.

This laptop may require a specific ALC295 mute-LED quirk or DMI entry.
