[MOD] Nexus 7 BEATS+ XLOUDER Jelly Bean Louder Audio Improvements
Are you having trouble hearing your Nexus 7 device when playing Music or Video files? Have you missed countless notifications due to trouble hearing them? You don't have to just chalk it up to old age and you don't need to check the battery in your hearing aid! It turns out that Jelly Bean comes with Pitifully low volume! There have been fixes like the Volume+ app which only fixed the volume issue on music playback, but it does nothing for skype, notifications, or earphone volume. This mod ups the volume across the board! This will work only if you are running a custom non stock kernel!
Simply download the mod, boot into recovery, and install zip from sdcard. No need to wipe volume. Now enjoy actually being able to hear your device!
