Default [Q] No Sound through screen mirror

I suddenly have no sound while doing screen mirroring with my Samsung ShareCast Hub. It was working fine, and then it just stopped outputting sound. I have verified that the device is working properly with my girlfriends Note 2. All other sound components working properly, verified with MHL adapter, headphones, and built-in speaker. All video streaming looks normal, as it did before the issue. I think it stopped working after an xposed framework update, but I forgot to take a backup. I am currently running 4.4.2 stock NC1 Rom and have verified every audio setting that I can think of but can't get it to work. I'm thinking that I may need to replace some of the screen mirroring components at the OS level from the original files, but I've not done much modification of this type before and could use some guidance.
