m15 R7, audio mute key not working

Hi @diego2c 

I wanted to inform you that I have escalated this matter to the relevant team, and I'll keep you updated on any developments regarding this topic as soon as I receive feedback from them.

@DELL-Nat M​ Any solution??

AWCC6 has been identified as the cause of damage to this component. Two weeks ago, my M15R7 upgraded from AWCC5 to AWCC6, and as a result, the mute key stopped working. Neither downgrading the BIOS nor replacing the keyboard helped. The engineer replaced the component "PART# H5R89" to get the mute key working again.

@A.Cooper​ What exactly is this component, can't find specific informations about it? My M17 R5 is out of warranty since one month but in germany they can be blamed for damages within 2 years but I must proof, that it was there fault. 

Hi all,

The team is aware that this issue is affecting many users. They are currently working on a long-term fix.

For now, please use the mute on the taskbar (when tapped the volume mute button becomes white with an x next to the speaker).

I first reported this issue on 29th of March the very next day the my laptop upgraded to AWCC 6x update. its been one month and the problem is still not resolved.

Sorry, I'm only getting back to your question now.

I was lucky that the engineer who repaired my laptop had encountered the same issue in his previous case. He tried replacing the keyboard, motherboard, and even resetting the system, but nothing worked. Eventually, he found out that the problem stemmed from a chip between the keyboard and motherboard malfunctioning due to an update in AWCC6. Simply replacing that component restored the mute key.

The AWCC6 update has caused the mute key to malfunction for many users. Currently, this issue seems to only affect Alienware users, and it's happening consistently after updating to AWCC6. It's evident that the update process of AWCC6 is causing the mute key malfunction. Regardless of whether users still have warranty coverage, you should repair this issue or provide free replacement of the damaged components for users.

@Jayvegad​ Alienware Per Key Keyboard firmware install this driver update for keyboard. It works with my Alienware m15 R7 without replacing that part.

Install this Per key Keyboard firmware update for keyboard. It works with my Alienware m15 R7 with Per Key keyboard.
