Custom kernel with sound boost >>> volume +
So I decided to Email SA Labs and ask if and when they were going to make an update so Equalizer would work with JellyBean. They answered back pretty quickly to my surprise with one sentence.
"Thx but there will be no more updates"
Well that sucks. :-(

Volume+ was the only difference between the GNex being a real phone and a pair of soup cans connected with a string (at least notification wise). I can't hear my phone ring when it's in my pocket, and forget about a text message waking you up, no matter how obnoxious the alert. This really sucks . I would have returned the phone after the first day, but I found Volume+ and it made the phone work like it's supposed to, so I kept it. Now that I'm stuck with it, it doesn't look like Google or Samsung is interested in fixing the problem...

There are other options though. [MOD] [GNEX] BEATS+XLOUDER! 4.1.2/4.2.2 | Galaxy Nexus > XDA <-- that is a fairly popular one which should work with any JB ROM.
