P14s/T14s AMD, MIC mute LED stopped working.

2021-07-22, 15:11 PM

I'm not sure what BIOS version did that, either 1.32 or 1.34.

 

Usually, I have the MIC muted by default, so the LED is always on.

I noticed today, it won't turn off so I went into BIOS and disabled & re-enabled the MIC.

After that from always ON the LED won't turn ON anymore.

 

MUTE/ UNMUTE works just the status LED won't turn on anymore.

 

( The LED itself is working since it blicks on BIOS reset or changing options )

 

Best Regards,

 

Gabriel

Seems to be 1.32 or even some earlier version, as MIC-LED does not work on my T14s AMD with 1.32 BIOS too.  

But mic mute still works as expected

I'll follow up with the FW team - this was an issue we had previously and had fixed so it sounds like they introduced a regression somehow.

On my LENOVO T14s (AMD) Gen 1. running MANJARO, the LED (F4) indicating the Microphone Mute has been working properly in the beginning with Kernel 5.4 (?).

In the past, I've seen this:

  • Kernel Version: 5.10.53-1-MANJARO (64-bit) → LED permanently OFF
  • Kernel Version: 5.10.56-1-MANJARO (64-bit) → LED permanantly ON
  • Kernel Version: 5.10.59-1-MANJARO (64-bit) → LED permanantly ON
  • Kernel Version: 5.13.11-1-MANJARO (64-bit) → LED permanantly ON

This issue is related only to the LED, muting and UNmuting the microphone works fine.

I'm having the same issue on my Thinkpad X13 Gen 1 running archlinux. After some reading, this issue might be related https://bugs.archlinux.org/task/71768

Thanks @stevechai & @MichaelLENO  

 

I've been able to reproduce the issue with it not working but I've been having trouble getting it to ever work with older kernels.

I'm going to do some more digging and ping the experts at Canonical
