There's an audio fix posted by another user a few posts before... Here's the link anyway: [XT1033][CM11] Audio fix. | Moto G | XDA Forum
It's really recommend trying to read the feedback from other users before installing a new build... That post wasn't really far behind... It was in the previous page!
Regards...
I actually flashed it over the #2 build and it worked but made music to sound a little bit weird so I had to use equalizer. But with the new build it didn't help. Music was broken.
