Mute Button LED Doesn't Work

Hello,
Although muting my audio works just fine, the mute button led doesn't work, My Laptop (Acer Nitro AN515-57, BIOS version V1.20) uses Intel HD Audio.

Pactl output

Codec Details

$ grep Codec /proc/asound/card*/codec*
/proc/asound/card0/codec#0:Codec: Nvidia GPU a0 HDMI/DP
/proc/asound/card1/codec#0:Codec: Realtek ALC295
/proc/asound/card1/codec#2:Codec: Intel Tigerlake HDMI

Following the Arch wiki I've tried all options under ALC22x/23x/25x/269/27x/28x/29x (and vendor-specific ALC3xxx models) found here.

Some modules didn't change anything, most just made the sound output stop, but 1, (asus-tx300) made the LED work regardless if it was muted or not, and it didn't interfere with the audio output.

If somebody here knows how to fix this or made it work with the same laptop as mine, then I would be very thankful for your input.
