Hi [NAME]  thank you for sharing update.  The Alienware m15/m17 R2 Realtek Audio Console Application | Driver Details | Dell US should restore the system's audio capability.

Hi, I have an Alienware M15 R2. I did a fresh factory reset and I have the latest AWCC (Alienware Command Center) version. The problem is my AWCC Audio Profiles are there, but they don't affect anything at all, I've tried to maximize or minimize all the EQ and Audio Effects etc. They just simply do not work. Although, "Master Volume" button, volume and changing between Headphones and Speakers buttons work. I want to use this feature of my laptop. What's the workaround? I've tried to remove Realtek Audio Console if it overlaps, but this didn't help too. Thanks.
m15 R2, AWCC audio profiles has no effect on audio!
